SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations or financial condition, business strategy and plans and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties, and other important factors that are in some cases beyond our control and may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will” or “would” or the negative of these words or other similar terms or expressions. These forward-looking statements include, but are not limited to, statements concerning the following:

•our ability to sell our platform to new customers;

•our ability to retain and expand use of our platform by our existing customers;

•our ability to effectively manage our growth;

•our ability to successfully obtain timely returns on our investments in initiatives relating to sales and marketing, research and development, and other areas;

•our ability to maintain our competitive advantages;

•our ability to maintain and expand our partner ecosystem;

•our ability to maintain the security of our platform and the security and privacy of customer data;

•our ability to successfully expand in our existing markets and into new markets;

•the attraction and retention of qualified employees and key personnel;

•our ability to successfully defend litigation brought against us;

•the impact of pandemics, inflation, war, other hostilities and other disruptive events on our business or that of our customers, partners, and supply chain or on the global economy;

•our ability to successfully remediate and prevent material weaknesses in internal controls over financial reporting; and

•the expenses associated with being a public company.

You should not rely on forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Quarterly Report on Form 10-Q primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition and operating results. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors described in the section titled “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report on Form 10-Q. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe that information provides a reasonable basis for these statements, that information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

The forward-looking statements made in this Quarterly Report on Form 10-Q relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1. Organization and Description of Business

Description of Business

Backblaze, Inc. and its subsidiaries (collectively, “Backblaze” or the “Company”) is a storage cloud platform, providing businesses and consumers with solutions to store and use their data. Backblaze provides these cloud services through purpose-built, web-scale software built on commodity hardware.

Note 2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 31, 2023. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as its annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of September 30, 2023, results of operations for the three and nine months ended September 30, 2023 and 2022, cash flows for the nine months ended September 30, 2023 and 2022, and stockholders' equity for the three and nine months ended September 30, 2023 and 2022. The results of operations for the three and nine months ended September 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.

Emerging Growth Company

The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an EGC.

Segment Information

The Company has a single operating and reportable segment. In reaching this conclusion, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources, and assess performance. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on an aggregated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Significant accounting policies

The Company’s significant accounting policies, certain of which have been updated below, are disclosed in the Company’s audited financial statements and related notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 31, 2023.

6

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, valuation of the Company’s ESPP expense, and accounting for taxes, including estimates for deferred tax assets, valuation allowance and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates.

Foreign Currency

The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company and its subsidiaries is USD. Transaction gains and losses that arise from exchange rate fluctuations on monetary transactions denominated in a currency other than the functional currency are included in general and administrative on the condensed consolidated statements of operations when realized.

Concentrations and Risks and Uncertainties

Liquidity. The Company believes that its existing cash, cash equivalents and short-term investments together with cash provided by operations, will be sufficient to support its working capital and capital expenditure requirements for at least the next 12 months. However, to achieve its continued growth and objectives, the Company will need to obtain additional sources of financing which may include entering into lease agreements, sale-leaseback arrangements, credit facilities, and other debt financing arrangements for the purpose of acquiring infrastructure equipment and to fund its operations. In the event that the Company requires additional financing, it may not be able to raise such financing on terms acceptable to us or at all. If the Company is unable to obtain additional sources of financing, raise additional capital or generate cash flows necessary to expand its operations and invest in continued innovation, it may not be able to compete successfully, which would harm its business, results of operations and financial condition.

Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, short-term investments, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and short-term investments with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the balance sheets. In addition, the Company uses City National Bank, a subsidiary of Royal Bank of Canada (“RBC”), for its banking needs. While the Company and its bank has not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption and uncertainty, which could put additional pressures on the Company’s bank and other banks, and may negatively impact the availability and costs for various banking and investment offerings.

Vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply and service disruptions that could harm the Company’s business.

Revenue. The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“Backblaze B2”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact to the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time.

Restructuring

Restructuring costs are comprised of severance costs related to workforce reductions. The Company recognizes restructuring charges when the liability is incurred. For involuntary terminations, employee termination benefits are accrued at the date (i) management has committed to a plan of termination, which includes identification of employees to be terminated and related information, (ii) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn, and (iii) employees have been notified of their termination dates and expected severance payments. For voluntary terminations, the Company recognizes a liability when the termination benefit has been irrevocably accepted by the employee.

Investments

The Company holds all investments on a held-to-maturity basis, and they are reported at amortized cost with realized gains or losses reported in earnings. The Company determines the appropriate classification of its investment in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date.

The Company will recognize an allowance for estimated credit losses on its held-to-maturity securities, using a forward-looking expected loss model, which reflects losses that are expected to be incurred over the life of the financial instrument. The Company uses a roll-rate method to determine the estimated credit losses using factors including historical global average default rates and expected recovery rates on similar credit quality, bond maturity and duration, along with historical experience, current conditions, and forecasts of future economic conditions, if available. The Company monitors the credit profile of its held-to-maturity securities on a periodic basis, using third party data to assess their credit ratings as well as any adverse conditions specifically related to the security.

The Company’s short-term investments include investment grade commercial paper with original maturities of 365 days or less at the date of purchase. Short-term investments are recorded at amortized cost on the balance sheet.

Accounting Pronouncements Recently Adopted

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires a financial asset measured at an amortized cost basis to be presented at the net amount expected to be collected, with further clarifications made more recently. For accounts receivables, unbilled receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2023 using the modified retrospective transition method with comparative periods continuing to be reported using the previous applicable guidance and determined that it did not have a material impact on its condensed consolidated financial statements.

Note 3. Revenues

Deferred Contract Costs

The Company’s amortization of deferred contract costs was $0.2 million for each of the three months ended September 30, 2023 and 2022, and was $0.7 million for each of the nine months ended September 30, 2023 and 2022. The amount of capitalized contract costs was $0.4 million as of both September 30, 2023 and December 31, 2022.

Deferred Revenue

Total deferred revenue was $27.2 million and $25.5 million as of September 30, 2023 and December 31, 2022, respectively. Revenue recognized for the three months ended September 30, 2023 and 2022 was $9.7 million and $9.2 million, respectively, and was $20.5 million and $19.3 million for the nine months ended September 30, 2023 and 2022, respectively, which was included in each deferred revenue balance at the beginning of each respective period. The Company’s deferred revenue as stated on its condensed consolidated balance sheets presented approximates its contract liability balance as of September 30, 2023 and December 31, 2022. The Company’s total deferred revenue balance as of September 30, 2023, approximates the aggregate amount of the transaction price allocated to remaining performance obligations (“RPOs”) as of that date. As of September 30, 2023, the Company's RPOs were $29.5 million. This amount includes deferred revenue arising from consideration invoiced for which the related performance obligations have not been satisfied, as well as future committed revenue for periods within current contracts with customers. As of September 30, 2023, the Company expects to recognize approximately 84% of its RPOs over the next 12 months, and substantially all of its RPOs over the next 24 months.

Note 5. Fair Value Measurements

The Company classifies its held-to-maturity investments, which are comprised of investment grade commercial paper, within Level 2 of the fair value hierarchy because the fair value of these securities are priced by using inputs based on non-binding market consensus that are primarily corroborated by observable market data or quoted market prices for similar

11

instruments. The Company’s cash equivalents on its condensed consolidated balance sheet included commercial paper with an amortized cost and estimated fair value of $3.0 million as of September 30, 2023.

There were no transfers between levels of the fair value hierarchy for the three and nine months ended September 30, 2023 and the year ended December 31, 2022, respectively. The Company held no assets or liabilities that were measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, respectively.

As of December 31, 2022, the Company had $169 thousand in restricted cash related to the letter of credit established according to requirements under a lease agreement, reported as a component of other current assets on the condensed consolidated balance sheets. As of September 30, 2023, this balance is no longer restricted as the lease agreement and associated letter of credit have been completed.

Additionally, the Company had $6.1 million and $4.3 million in restricted cash as of September 30, 2023 and December 31, 2022, respectively, related to the line of credit agreement with City National Bank. See Note 11 for further details.

Note 10. Commitments and Contingencies

Finance Leases and Lease Financing Obligations

The Company enters into finance lease arrangements to obtain hard drives and related equipment for its data center operations. The term of these agreements primarily range from three to four years and certain of these arrangements have optional renewals to extend the term of the lease generally at a fixed price. Contingent rental payments are generally not included in the Company’s finance lease agreements. Finance leases are generally secured by the underlying leased equipment. The Company's finance leases have original lease periods expiring between 2023 and 2026. Finance leases are included in property and equipment, net on the Company’s condensed consolidated balance sheet.

As of September 30, 2023, the weighted average remaining lease term for finance lease and lease financing obligation agreements was 1.9 years and the weighted average discount rate for finance leases was 10.8%.

For the Company’s assets acquired through finance lease and lease financing obligation agreements, which are related to sale-leaseback agreements, depreciation expense was $3.9 million and $3.5 million for the three months ended September 30, 2023 and 2022, respectively, and was $11.2 million and $9.7 million for the nine months ended September 30, 2023 and 2022, respectively. Depreciation expense on assets acquired through the Company’s finance leases and lease financing obligations is included in cost of revenue in its condensed consolidated statements of operations.

During the three months ended September 30, 2023, total finance lease costs were $4.4 million, of which interest expense was approximately $0.7 million, and total lease financing obligation costs were $0.3 million, of which interest expense was approximately $0.1 million. During the three months ended September 30, 2022, total finance lease costs were $4.1 million, of which interest expense was approximately $0.9 million, and total lease financing obligation costs were $0.3 million, of which interest expense was approximately $0.1 million.

During the nine months ended September 30, 2023, total finance lease costs were $12.5 million, of which interest expense was approximately $2.2 million, and total lease financing obligation costs were $1.0 million, of which interest expense was approximately $0.2 million. During the nine months ended September 30, 2022, the total finance lease costs were $11.4 million, of which interest expense was approximately $2.5 million, and total lease financing obligation costs were $1.0 million, of which interest expense was approximately $0.3 million. The cash paid for interest on interest on finance lease and lease financing obligations was $2.4 million and $2.8 million for the nine months ended September 30, 2023 and 2022, respectively.

During the nine months ended September 30, 2023, the Company entered into one sale-leaseback arrangement with a vendor to provide $2.5 million in cash proceeds for previously purchased hard drives and related equipment. The Company concluded the related lease arrangements would be classified as a lease financing obligation as the Company is reasonably certain to exercise the purchase option within the arrangement. Therefore, the transaction was deemed a failed sale-leaseback and was accounted for as a financing arrangement. The assets continue to be depreciated over their useful lives, and payments are allocated between interest expense and repayment of the financing liability. The Company did not enter into any sale-leaseback arrangements during the nine months ended September 30, 2022.

The future minimum commitments for these finance leases and lease financing obligations as of September 30, 2023 were as follows (in thousands):

Operating Leases

The Company leases its facilities for data centers and office space under non-cancelable operating leases with various expiration dates. Certain lease agreements include renewal options to extend the lease term at a price to be determined upon exercise. These options are not reasonably certain to be exercised and therefore are not factored into the determination of lease payments. Contingent rental payments are generally not included in the Company’s lease agreements. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company's leases have original lease periods expiring between 2023 and 2031. The Company did not have a material amount of short-term leases as of September 30, 2023.

As of September 30, 2023, the weighted average remaining lease term for operating leases was approximately 5.7 years and the weighted average discount rate for operating leases was approximately 7.5%.

In July 2023, the Company entered into an operating lease agreement for purposes of consolidating and moving out of two offices into one, resulting in the recognition of $5.3 million of operating right-of-use assets and $5.2 million of operating lease liabilities, current and non-current, on its condensed consolidated balance sheet as of September 30, 2023.

The future minimum commitments for these operating leases as of September 30, 2023 were as follows (in thousands), which excludes amounts allocated to services under operating lease agreements that are considered non-lease components:

Year Ending December 31,
Remaining of 2023	$	640
2024	2,464
2025	2,026
2026	2,076
2027	2,131
Thereafter	3,558
Total future minimum operating lease commitments	12,895
Less imputed interest	(2,379)
Total liability	$	10,516

Non-lease components included in the Company’s colocation lease agreements are related to non-tangible utilities and services used in its data center operations. The Company used judgment and third-party data in determining the stand-alone price for allocating consideration to lease and non-lease components under these colocation lease agreements, such as, the price of utilities as compared to its tangible data center footprint within each colocation facility.

The future minimum commitments for the Company’s non-cancellable contractual obligations as of September 30, 2023 for non-lease components were as follows (in thousands):

15

Year Ending December 31,
Remaining of 2023	$	1,307
2024	4,240
2025	2,623
2026	2,603
2027	2,679
Thereafter	6,330
Total future minimum commitments	$	19,782

Rental expense related to the Company’s operating leases for both lease and non-lease components was $2.1 million and $1.9 million for the three months ended September 30, 2023 and 2022, of which $1.8 million and $1.4 million is included in cost of revenue in its condensed consolidated statement of operations, respectively. Rental expense related to lease components was $0.7 million for each of the three months ended September 30, 2023 and 2022. Total operating lease cost was $2.6 million and $2.3 million for the three months ended September 30, 2023 and 2022, respectively, which does not include costs related to services.

Rental expense related to the Company’s operating leases for both lease and non-lease components was $6.2 million and $4.7 million for the nine months ended September 30, 2023 and 2022, of which $5.1 million and $3.6 million is included in cost of revenue in its condensed consolidated statement of operations as of such dates, respectively. Rental expense related to lease components was $2.2 million and $2.0 million for the nine months ended September 30, 2023 and 2022, respectively. Total operating lease cost was $7.9 million and $5.8 million, for the nine months ended September 30, 2023 and 2022, respectively, which does not include costs related to services.

Other Contractual Commitments

Other non-cancellable commitments relate mainly to service agreements used to facilitate the Company’s infrastructure operations. As of September 30, 2023, the Company had non-cancelable purchase commitments of $2.5 million and $0.7 million payable during the remainder of the year ending December 31, 2023 and the year ending December 31, 2024, respectively.

401(k) Plan

The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees. Contributions to the 401(k) plan are discretionary. The Company contributed $0.5 million and $0.4 million to the 401(k) plan during the three months ended September 30, 2023 and 2022, respectively, and $1.4 million and $1.2 million for the nine months ended September 30, 2023 and 2022, respectively.

Legal Matters

The Company is involved from time to time in various claims and legal actions arising in the ordinary course of business. While it is not feasible to predict or determine the ultimate outcome of these matters, the Company believes that there are not any current legal proceedings that are likely to have a material adverse effect on its financial position, results of operations or cash flows. However, the results of legal proceedings are inherently unpredictable and litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.

Accrued VAT Liability

The Company has calculated a liability for uncollected and unpaid VAT, which is generally assessed by various taxing authorities on services the Company provides to its customers. The Company accrues an amount that it considers probable to be collected and can be reasonably estimated. Based on the Company’s analysis, its total accrual for VAT payable was $1.0 million and $1.2 million as of September 30, 2023 and December 31, 2022, respectively.

Indemnification

16

The Company enters into indemnification provisions under agreements with other parties from time to time in the ordinary course of business. The Company has agreed in certain circumstances to indemnify and defend the indemnified party for claims and related losses suffered or incurred by the indemnified party from third-party claims due to the Company’s activities or non-compliance with certain representations and warranties made by the Company. It is not possible to determine the maximum potential loss under these indemnification provisions due to the Company’s limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. No losses have been recorded in the condensed consolidated statements of operations in connection with the indemnification provisions.

Note 11. Debt

Credit Facility

During April 2022, the Company entered into a second amendment to its revolving credit agreement (as amended, the “RCA”) with City National Bank (“Lender”). Under this amendment, the amount available to be borrowed was increased to $30.0 million from $9.5 million. During January 2023, the Company entered into a third amendment to the RCA. Under this amendment, advances on the line of credit will bear monthly interest at a variable rate equal to, at the Company’s discretion, (a) the average Secured Overnight Financing Rate (“SOFR”) plus 2.00%, or (b) the base rate. The base rate under the RCA is a rate equal to the greater of (i) 3.00% or (ii) the prime rate most recently announced by the Lender. There were no other material changes to the RCA as a result of the amendment. As of September 30, 2023, the Company had an outstanding balance of $6.1 million and the total amount available to the Company to be borrowed was $23.9 million.

Under the RCA, the outstanding balance of $6.1 million as of September 30, 2023 was collateralized by cash held by the Company. As such, the Company held $6.1 million in cash that it deemed to be restricted and is included in restricted cash, current on the Company’s condensed consolidated balance sheet as of September 30, 2023. With prior written notice to the Lender, the Company has the right, at any time prior to the maturity date in September 2024, to terminate the RCA. In the event of such termination, the aggregate principal of the then outstanding amounts, including any accrued interest to date, shall be repaid and the restrictions on the associated collateralized cash would be released. The Company classifies the facility as debt facility, current on its condensed consolidated balance sheet as of September 30, 2023.

As of September 30, 2023, the interest rate associated with the outstanding balance under the RCA was 7.4%, which is a per annum rate. Interest payments on outstanding borrowing are due on the last day of each monthly interest period and payments for the commitment fee are due at the end of each calendar quarter. Total interest expense related to the RCA was $0.2 million and $0.4 million for the three and nine months ended September 30, 2023, respectively. Total interest expense related to the RCA was less than $0.1 million for the three and nine months ended September 30, 2022, respectively.

Insurance Premium Financing Agreement

Effective November 2022, the Company entered into an insurance policy with annual premiums totaling $2.1 million. The Company executed a finance agreement with AFCO Premium Credit LLC over a term of twelve months, with an annual interest rate of 4.5%, that finances the payment of the total premiums owed. The finance agreement required a $0.5 million down payment, with the remaining $1.5 million plus interest paid over three quarterly installments. These quarterly payments started on February 10, 2023. As of September 30, 2023, the balance of this finance agreement was fully paid.

Note 12. Stockholders’ Equity

Common Stock. From the time of its initial public offering through July 5, 2023, the Company had two outstanding classes of common stock, Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock were identical, except for voting, transfer, and conversion rights. On July 6, 2023, all of the Company’s then-outstanding shares of the Company’s Class B common stock were automatically converted (the “Conversion”) into the same number of shares of Class A common stock pursuant to the terms of the Company’s Amended and Restated Certificate of Incorporation. No additional shares of Class B common stock will be issued following the Conversion. In addition, on July 7, 2023, the Company filed a Certificate of Retirement with the Secretary of State of the State of Delaware effecting the retirement of the shares of Class B common stock that were issued but no longer outstanding following the Conversion. As of September 30, 2023, the Company’s sole outstanding class of common stock was its Class A common stock.

The Company had reserved shares of common stock for future issuance as follows:

	September 30, 2023	December 31, 2022
2011 Equity Incentive Plan (“2011 Plan”)
Options outstanding	8,743,758	10,862,094

Note 13. Stock-Based Compensation

Equity Incentive Plan

Share Reserve. As of September 30, 2023, the number of shares of common stock available for issuance under the 2021 Equity Incentive Plan equaled the sum of 14,662,500 shares, plus up to approximately 13,719,000 shares subject to awards granted under the 2011 Plan that expire, forfeit or are repurchased following the effective date of the 2021 Plan. In addition, the number of shares reserved for issuance under the 2021 Plan will be increased automatically on the first business day of each of the Company’s fiscal years, by a number equal to the lowest of (i) 4,784,100 shares, (ii) 5% of the shares of Class A common stock outstanding on the last business day of the prior fiscal year; or (iii) the number of shares determined by the Board of Directors. Pursuant to this evergreen provision, the Company increased the number of shares reserved under the 2021 Plan by 809,916 and 411,399 shares of Class A common stock during January 2023 and 2022, respectively.

In general, to the extent that any awards under the 2021 Plan are forfeited, terminate, expire or lapse without the issuance of shares, or if the Company reacquires the shares subject to awards granted under the 2021 Plan, those shares will again become available for issuance under the 2021 Plan, as will shares applied to pay the exercise or purchase price of an award or to satisfy tax withholding obligations related to any award.

Restricted Stock Units

Restricted stock units (“RSUs”) granted under the 2021 Plan generally vest based on continued service over a one-to-four-year period for employees, and over a one year period for non-employee directors.

RSU activity for the nine months ended September 30, 2023 was as follows:

	Shares	Weighted-average grant date fair value per share
Unvested balance as of December 31, 2022	3,716,061	$	6.60
Granted	4,214,704	$	5.04
Vested	(1,877,745)	$	6.23
Forfeited	(239,510)	$	5.44
Unvested balance as of September 30, 2023	5,813,510	$	5.64

18

Stock Options

Stock Options. Stock options granted under the Company’s equity plans generally vest based on continued service over four years and expire ten years from the date of grant.

The following table summarizes the Black-Scholes option pricing model weighted-average assumptions used in estimating the fair value of stock options granted to employees during the nine months ended September 30, 2022. No stock options were granted during the nine months ended September 30, 2023.

	Nine Months Ended September 30, 2022
Expected term (in years)	6.0
Expected volatility	49.0	%
Risk-free interest rate	1.20	%
Expected dividend yield	—	%

Expected term. For stock options considered to be “plain vanilla” options, the Company estimates the expected term based on the simplified method, which is essentially the weighted average of the vesting period and contractual term, as the Company’s historical share option exercise experience does not provide a reasonable basis upon which to estimate the expected term.

Expected volatility. The Company performed an analysis using the average volatility of a peer group of representative public companies with sufficient trading history over the expected term to develop an expected volatility assumption.

Risk-free interest rate. Based upon quoted market yields for the United States Treasury debt securities for a term consistent with the expected life of the awards in effect at the time of grant.

Expected dividend yield. Because the Company has never paid and has no intention to pay cash dividends on common stock, the expected dividend yield is zero.

A summary of equity award activity under the Company’s equity plans and related information is as follows (in thousands, except share, price and year data):

	Shares available for grant	Outstanding stock options	Weighted- average exercise Price		Weighted- average remaining contractual life (years)	Aggregate intrinsic value
Balance as of December 31, 2022	1,836,566	12,371,281	$	5.74	6.07	$	32,385
Shares authorized	9,102,074
Options granted	—	—	—
Options exercised	—	(1,844,602)	1.79
Options canceled	428,189	(428,189)	11.31
RSU award activity	(3,975,194)	—
Balance as of September 30, 2023	7,391,635	10,098,490	$	6.22	5.74	$	18,855
Vested and exercisable as of September 30, 2023		8,075,929	$	4.89	5.27	$	17,967

The weighted-average grant-date fair value of options granted during the nine months ended September 30, 2022 was $6.26. The intrinsic value of options exercised for the nine months ended September 30, 2023 and 2022 was $6.1 million and $9.1 million, respectively. Aggregate intrinsic value represents the difference between the exercise price of the options

19

and the estimated fair value of the Company’s common stock at the time of exercise. The aggregate grant-date fair value of options vested was $6.8 million and $8.0 million during the nine months ended September 30, 2023 and 2022, respectively.

ESPP

As of September 30, 2023, the ESPP reserved and authorized the issuance of up to a total of 956,800 shares of Class A common stock to participating employees. Pursuant to its evergreen provision, the Company increased the number of shares reserved under the ESPP by 667,874 and 607,696 during January 2023 and 2022, respectively.

During the nine months ended September 30, 2023, 348,555 shares of Class A common stock have been purchased under the ESPP. The fair value of the purchase rights under the ESPP was estimated using the Black-Scholes option pricing model with a similar methodology for determining inputs as the Company’s stock options, as described above.

The Company recorded stock-based compensation expense under this plan of $0.9 million and $0.8 million for the three months ended September 30, 2023 and 2022, respectively, of which the Company capitalized $0.2 million and $0.2 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software. The Company recorded stock-based compensation expense under this plan of $2.8 million and $2.4 million for the nine months ended September 30, 2023 and 2022, respectively, of which the Company capitalized $0.7 million and $0.3 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

As of September 30, 2023, the total unrecognized stock-based compensation expense related to the ESPP was $1.8 million and is expected to be recognized over a weighted average period of one year. As of September 30, 2023, $1.2 million had been withheld on behalf of employees, respectively.

The following table summarizes the Black-Scholes option pricing model assumptions used in estimating the fair value of the stock purchase rights under the ESPP during the three and nine months ended September 30, 2023 and 2022, respectively.

	Three Months Ended September 30,			Nine months ended September 30,
	2023	2022		2023		2022

Stock-Based Compensation Expense

Stock-based compensation expense included in the condensed consolidated statements of operations was as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Cost of revenue	$	653	$	353	$	1,456	$	977
Research and development	2,865		1,828		6,786		5,066
Sales and marketing	2,747		1,539		6,616		3,906

Total stock-based compensation expense	$	7,958	$	4,830	$	18,670	$	13,011

During the nine months ended September 30, 2023 and 2022, the Company capitalized $3.7 million and $1.8 million, respectively, of stock-based compensation for the development of internal-use software. As of September 30, 2023, total compensation cost related to stock options and RSUs not yet vested was $13.0 million and $30.4 million, respectively, which will be recognized over a weighted-average period of two years for stock options and RSUs.

20

Bonus Plan

During March 2022, the Company’s Compensation Committee approved a new bonus structure (“Bonus Plan”) for its employees. The Bonus Plan is contingent upon the achievement of annual corporate performance targets. In each respective calendar year, the Company accrues for the Bonus Plan. The actual payout amount is determined by the Company’s Compensation Committee based on the actual achievement with respect to the annual performance targets and paid in the subsequent year in the variable number of RSUs equal to the payout amount. These RSU’s are fully vested as they were earned (and expensed) prior to the payout. Participants must remain employed with the Company through the date of payout to maintain eligibility under the Bonus Plan.

Pursuant to the Bonus Plan, during February 2023 the Company’s Compensation Committee approved the issuance of approximately 288,000 RSUs that immediately vested based on actual performance against the performance targets for 2022. The Company recognized $0.7 million and $1.7 million in stock-based compensation during the three and nine months ended September 30, 2022, respectively, of which the Company capitalized $0.1 million and $0.2 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

During February 2023, the Company’s Board of Directors approved annual corporate performance targets under its Bonus Plan for 2023 for its employees. If these performance targets are met during 2023, employees will be paid out under the Bonus Plan in RSUs in 2024. As a result, the Company recognized $1.7 million and $2.6 million in stock-based compensation during the three and nine months ended September 30, 2023, respectively, based on progress made towards these performance targets. During the three and nine months ended September 30, 2023, the Company capitalized $0.2 million and $0.4 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

Note 14. Net Loss per Share Attributable to Common Stockholders

The Company computes net loss per share for periods prior to the Conversion using the two-class method required for multiple classes of common stock and participating securities. Prior to the Conversion, shares of Class A and Class B were the only outstanding equity in the Company. The rights of the holders of the Class A common stock and Class B common stock were identical, except with respect to voting and conversion. Accordingly, the Class A common stock and Class B common stock shared equally in the Company’s net losses.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents during the period. For purposes of this calculation, the Company’s stock options, share purchase rights pursuant to the Company’s ESPP, and unvested restricted stock are considered to be potential common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.

As discussed above in Note 12, on July 6, 2023, all of the Company’s then-outstanding shares of Class B common stock, par value $0.0001 per share, were automatically converted into the same number of shares of Class A common stock, par value $0.0001 per share, pursuant to the terms of the Company’s Amended and Restated Certificate of Incorporation. No additional shares of Class B common stock will be issued following the conversion. In addition, on July 7, 2023, the Company filed a Certificate of Retirement with the Secretary of State of the State of Delaware effecting the retirement of the shares of Class B common stock that were issued but no longer outstanding following the Conversion. Prior to the Conversion, the rights of the holders of the Class A common stock and Class B common stock were identical, except with respect to voting, transfer and conversion. As the liquidation and dividend rights were identical, the Company’s undistributed earnings or losses were allocated on a proportionate basis among the holders of Class A and Class B common stock. As a result, the net loss per share attributed to common stockholders was, therefore, the same for both Class A and Class B common stock on an individual or combined basis.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except share and per share data):

21

	Three Months Ended September 30,								Nine Months Ended September 30,
	2023				2022				2023				2022
Numerator:	Class A		Class B		Class A		Class B		Class A		Class B		Class A		Class B
Net loss attributable to common stockholders	$	(15,744)	$	(311)	$	(5,865)	$	(6,935)	$	(34,406)	$	(13,099)	(14,185)		$	(22,720)
Denominator for basic and diluted net loss per share:
Weighted-average shares used in computing net loss per share attributable to Class A and Class B common stockholders – basic and diluted	35,953,930		711,265		14,659,262		17,335,129		25,534,082		9,721,590		12,009,620		19,235,449
Net loss per share attributable to common stockholders – basic and diluted	$	(0.44)	$	(0.44)	$	(0.40)	$	(0.40)	$	(1.35)	$	(1.35)	$	(1.18)	$	(1.18)

Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented are as follows:

	September 30,
	2023	2022
RSUs	5,813,510	2,238,357
Stock options	10,098,490	12,982,199
Shares issuable pursuant to the ESPP	290,427	300,785
Total	16,202,427	15,521,341

Note 15. Restructuring

In January 2023, the Company initiated measures to reduce headcount to pursue greater cost efficiency and align strategic initiatives. These measures were substantially completed by June 30, 2023, and the total cost was $3.6 million. During this period, approximately 1% and 4% of the Company’s workforce terminated employment, which were voluntary and involuntary terminations, respectively. As a result, the Company incurred employee termination expenses and other associated costs.

22

A summary of the restructuring charges as reported on the condensed consolidated statements of operations for the three and nine months ended September 30, 2023, of which $0.7 million were related to involuntary terminations, is as follows (in thousands):

	Severance and other Personnel Costs
	Three Months Ended September 30, 2023		Nine Months Ended September 30, 2023
Research and development	$	12	$	2,311
Sales and marketing	—		1,025
General and administrative	—		280
Total	$	12	$	3,616

The following table is a summary of the charges in the severance and other personnel liabilities, included within accrued expenses and other current liabilities on the condensed consolidated balance sheets, related to the workforce reduction (in thousands):

Balance as of January 1, 2023	$	—
Severance and other personnel costs	$	3,616
Cash payments during the period	$	(3,604)
Balance as of September 30, 2023(1)	$	12

(1) The Company expects the remaining severance and termination related liabilities to be substantially paid out in cash during the fourth quarter of 2023.

Note 16. Income Taxes

The Company is subject to U.S. federal and state income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter.

The effective tax rate for each of the three and nine months ended September 30, 2023 and 2022 was zero as the Company has incurred continuous operating losses. The Company recorded no income tax provision or benefit during the three and nine months ended September 30, 2023 and three months ended September 30, 2022. The Company recorded an income tax benefit of less than $0.1 million during the nine months ended September 30, 2022.

On August 16, 2022, the Inflation Reduction Act was enacted in the U.S. and introduced a 15% alternative minimum tax based on the financial statement income of certain large corporations (“CAMT”) and an excise tax of 1% of stock repurchases, effective January 1, 2023. There was no impact on the Company’s provision for income taxes from the Inflation Reduction Act for the three and nine months ended September 30, 2023. The Company is continuing to evaluate the various provisions of the Inflation Reduction Act and does not anticipate the impact, if any, will be material to the Company.

Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against its otherwise recognizable net deferred tax assets.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our audited financial statements and the related notes and the discussion under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations" for the year ended December 31, 2022 included in the Annual Report on Form 10-K for the year ended December 31, 2022. This discussion, particularly information with respect to our future results of operations or financial condition, business strategy and plans, and objectives of management for future operations, includes forward-looking statements that involve risks and uncertainties as described under the heading "Special Note About Forward-Looking Statements" in this Quarterly Report on Form 10-Q. You should review the disclosure under the heading "Risk Factors" in this Quarterly Report on Form 10-Q for a discussion of important factors that could cause our actual results to differ materially from those described or implied in these forward-looking statements. Our historical results are not necessarily indicative of the results that may be expected for any period in the future. Unless the context otherwise requires, all references in this report to "Backblaze," the “Company”, "we," "our," "us," or similar terms refer to Backblaze, Inc. and its consolidated subsidiaries.

Overview

We are a leading specialized storage cloud platform, providing businesses and consumers cloud services to store, use, and protect their data in an easy and affordable manner. We provide these cloud services through a purpose-built, web-scale software infrastructure built on commodity hardware. We believe that by substantially reducing the complexity and frustration of storing, using, and protecting data, we can empower customers to focus on their core business operations. Through our blog and culture of transparency, we have built a community of millions of readers and brand advocates. Referrals from our community of brand advocates, combined with our highly efficient and primarily self-serve customer acquisition model and an ecosystem of thousands of partners, have allowed us to attract more than 500,000 customers as of December 31, 2022. These customers use our Storage Cloud platform across more than 175 countries to grow and protect their business data on our over 3 exabytes, or 3 trillion megabytes, of data storage under management.

Our Backblaze Storage Cloud provides a platform that is the foundation for our B2 Cloud Storage Infrastructure-as-a-Service (IaaS) offering and our Backblaze Computer Backup Software-as-a-Service (SaaS) offering. B2 Cloud Storage enables customers to store data, developers to build applications, and partners to expand their use cases. The amount of data stored in this cloud service can scale up and down as needed primarily on a pay-as-you-go basis or can be paid for on a capacity basis for greater predictability, which we refer to as our B2 Reserve offering. Backblaze Computer Backup automatically backs up data from laptops and desktops for businesses and individuals. This cloud backup service offers easily understood primarily flat-rate pricing to continuously back up a virtually unlimited amount of data.

We believe that focusing on storage use cases and promoting an open ecosystem allows us to integrate well with a broad range of partners. We have consistently invested in our technology platform and highly efficient content-driven and primarily self-serve go-to-market strategy, allowing us to achieve customer, community, and product milestones.

During the third quarter of 2023, we announced pricing increases and product updates across our Computer Backup and B2 Cloud Storage products, which generally became effective October 3, 2023. These price increases are phased in over time based on the type of offering, subscription plan and renewal timing. As part of our leadership in the open cloud movement, we also announced free egress, significant performance improvements, and new functionality to increasingly support our customers’ ability to break free from limitations on their data.

Automatic Conversion of our Class B Common Stock

In July 2023, the holders of shares of our Class B common stock held a special meeting (the “Special Meeting”). At the Special Meeting, the holders of a majority of the Company’s then outstanding shares of Class B common stock approved the conversion of all outstanding shares of Class B common stock into the same number of shares of our Class A common stock effective July 6, 2023. As a result, our dual class structure was eliminated. All holders of our outstanding Class A common stock are entitled to one vote per share that they hold and no further shares of Class B common stock will be issued.

Factors Affecting Our Performance

We believe that the future growth and performance of our business will depend on several factors, including the following:

Scale Self Service Customer Acquisition

Our business depends, in part, on our ability to add new customers. We believe there is a significant opportunity to further grow our customer base by continuing to make investments in sales and marketing. We plan to continue investing in our customer acquisition and inbound demand generation activities, which is driven predominantly by our blog content, our case studies, social sharing, earned media, and our self-serve sign up model. We intend to leverage this model as an efficient approach to attract new customers, turning them into brand advocates, partners, and more referrals. Furthermore, we plan to continue to leverage our paid lead generation and outbound sales motion to increasingly grow in the mid-market.

We also plan to continue to build our ecosystem of partners. We believe that delivering our Storage Cloud solutions through our alliance, developer, and MSP partnerships is an area of opportunity for us. By adding more partners and deepening our relationships with them, we expand our use cases and drive new customer acquisition.

Scale Sales-Assisted Efforts

We believe an increasingly important complement to our self-serve customer acquisition model is our targeted inside Sales team that is focused on a low-touch “sales-assisted” model that supports our larger customers if the need arises. This team focuses on inbound inquiries, outbound prospecting targeting specific use cases, and volume expansion of our self-serve customers.

Expansion Within Existing Customers

Our future success will depend, in part, on our ability to increase usage and adoption of our solutions with existing customers. We intend to increase revenue from existing customer relationships through the development of additional features and use cases, expanding our Customer Success initiatives, and natural customer data growth. We have developed add-on services, such as Extended Version History and multi-region selection, which customers pay for on top of existing offerings. Examples of expanding use cases include utilizing Backblaze for additional purposes such as media storage, hybrid cloud support, analytics repositories, and others. We also plan to grow our Customer Success initiatives to ensure customers avail themselves of the full benefits of our platform, thus resulting in increased adoption. As these customers continue to generate, store, and back up data, their use of our platform increases, creating natural opportunities for revenue expansion.

Continued Platform Investment and New Product Launches

We are committed to delivering market-leading products that continue to make cloud storage and backup easy. We believe we must maintain our product quality and strength of our brand in order to retain the current customer base as well as drive further revenue growth in our business. We intend to continue investing in our research and development activities to build upon our strong position in the technology community. We also plan to launch new products that are adjacent to our current offerings, which will provide us with the ability to further cross-sell and upsell.

Investments for Continued Scaling

We are focused on our long-term revenue potential and building out our infrastructure to sustain that growth. On a routine basis, we plan to focus resources on optimizing the efficiency of our data storage. In some scenarios, we may choose to pass on potential cost savings to the customer, but in other scenarios we may choose to reinvest cost savings back into infrastructure and design.

International Expansion

While our sales and marketing investments have primarily focused on the United States, our existing customer base spans more than 175 countries, with 28% of our total revenue originating outside of the United States for the nine months ended September 30, 2023. We believe international expansion may represent a meaningful opportunity to generate further demand for our solutions in international geographies. We may invest in our operations internationally to reach new

25

We monitor the key business metrics set forth below to help us evaluate our business and growth trends, establish budgets, measure the effectiveness of our sales and marketing investments, and assess operational efficiencies. The calculation of the key metrics discussed below may differ from other similarly titled metrics used by other companies, securities analysts or investors.

Net Revenue Retention Rate

We believe the growth in the use of our platform by our existing customers is an important measure of the health of our business and our future growth prospects. We measure this growth by monitoring our overall net revenue retention rate, which measures our ability to retain and expand revenue from existing customers. We believe that we can drive this metric by continuing to focus on our customers and by adding additional products and functionality to our platform.

Our overall net revenue retention rate is a trailing four-quarter average of the recurring revenue from a cohort of customers in a quarter as compared to the same quarter in the prior year. We calculate our overall net revenue retention rate for a quarter by dividing (i) recurring revenue in the current quarter from any accounts that were active at the end of the same quarter of the prior year by (ii) recurring revenue in the current corresponding quarter from those same accounts. Our overall net revenue retention rate includes any expansion of revenue from existing customers and is net of revenue contraction and customer attrition, and excludes revenue from new customers in the current period. Our net revenue retention rate for B2 Cloud Storage and Computer Backup is calculated in the same manner as our overall net revenue retention rate based on the revenue from our B2 Cloud Storage and Computer Backup solutions, respectively.

Gross Customer Retention Rate

We use gross customer retention rate to measure our ability to retain our customers. Our gross customer retention rate reflects only customer losses and does not reflect the expansion or contraction of revenue we earn from our existing customers. We believe our high gross customer retention rates demonstrate that we provide a vital service to our customers, as the vast majority of our customers tend to continue to use our platform from one period to the next. To calculate our gross customer retention rate, we take the trailing four-quarter average of the percentage of cohort of customers who were active at the end of the quarter in the prior year that are still active at the end of the current quarter. We calculate our gross customer retention rate for a quarter by dividing (i) the number of accounts that generated revenue in the last month of the current quarter that also generated recurring revenue during the last month of the corresponding quarter in the prior year, by (ii) the number of accounts that generated recurring revenue during the last month of the corresponding quarter in the prior year.

Annual Recurring Revenue

We define annual recurring revenue (ARR) as the annualized value of all B2 Cloud Storage and Computer Backup arrangements as of the end of a period. Given the renewable nature of our business, we view ARR as an important indicator of our financial performance and operating results, and we believe it is a useful metric for internal planning and analysis. ARR is calculated based on multiplying the monthly revenue from all B2 Cloud Storage and Computer Backup arrangements, which represent greater than 98% of our total revenue for the periods presented (and excludes Physical Media revenue), for the last month of a period by 12. Our annual recurring revenue for B2 Cloud Storage and Computer Backup is calculated in the same manner as our overall annual recurring revenue based on the revenue from our Computer Backup and B2 Cloud Storage solutions, respectively. See Note 3 to our financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information on revenue from B2 Cloud Storage and Computer Backup arrangements.

ARR does not have a standardized meaning and is therefore unlikely to be comparable to similarly titled measures presented by other companies. ARR should be viewed independently of revenue and is not intended to be combined with or to replace that item. ARR is not a forecast and the active contracts at the end of a reporting period used in calculating ARR may or may not be extended or renewed by our customers.

While ARR is not a guarantee of future revenue, we consider over 98% of our revenue recurring in nature for the periods presented. As noted above, our gross customer retention rate has been consistent over the periods presented at approximately 90%. Although B2 Cloud Storage is paid for by customers in arrears, we recognize revenue in the month these storage services are delivered, and consider this revenue recurring as customers are charged as long as their data is stored with us. Further, during the periods presented, customers who store data with us generally increase the amount of their data stored over time, as evidenced by our B2 Cloud Storage net revenue retention rate of 120% as of September 30, 2023. Fees from B2 Cloud Storage (consumption-based arrangements) are recognized as services are delivered. Computer Backup (subscription-based arrangements) revenue is recognized on a straight-line basis over the contractual term of the arrangement beginning on the date that the service commences, provided that all other revenue recognition criteria have been met. See Note 2 to our audited financial statements for the year ended December 31, 2022 included in our Annual Report on Form 10-K for details on our revenue recognition policy. Additional limitations of ARR include the fact that consumption-based revenue is not guaranteed for future periods, although we believe that our high historic gross customer retention rate is indicative of ARR, and the fact that our subscription terms can be on a monthly basis, although the significant majority of our customers have subscription terms of one year or longer during the periods presented above.

Impact of COVID-19

The worldwide spread of COVID-19 had a significant impact on the global economy.

For additional details, see the section titled “Risk Factors - The COVID-19 pandemic has impacted how we, our customers, and our partners are operating, and any re-emergence of the pandemic could result in a material adverse effect on our business.”

Key Components of Results of Operations

Revenue

We generate revenue primarily from our Backblaze B2 Cloud Storage and Backblaze Computer Backup cloud services offered on our platform. Our platform is offered to our customers primarily through either a consumption or a subscription-based arrangement through B2 Cloud Storage and Backblaze Computer Backup, respectively. Our subscription arrangements generally range in duration from one month to 24 months, for which we bill our customers up front for the entire period. Our consumption-based arrangements do not have a contractual term and are billed monthly in arrears.

Consumption-based revenue is variable and is related to fees charged for our customers’ use of our platform and is recognized as revenue in the period in which the consumption occurs. For our subscription arrangements, we provide our cloud services evenly over the contractual period, for which revenue is recognized on a straight-line basis over the contract term beginning on the date that the service is made available to the customer.

27

In support of our platform, we also derive revenue from products offered to our customers for the ability to securely restore data using a USB drive (USB Restore) and for migrating large data sets to our platform using our proprietary Fireball device. Revenue from USB Restore is recognized as our products are delivered to our customers. Revenue recognized from customer rentals of our Fireball device is time-based.

Cost of Revenue and Gross Margin

Cost of revenue consists of our expenses in providing our platform and cloud services to customers. These expenses include operating in co-location facilities, network and bandwidth costs, and depreciation of our equipment and finance leased equipment in co-location facilities. Personnel-related costs associated with customer support and maintaining service availability, including salaries, benefits, bonuses, and stock-based compensation are also included. Cost of revenue also includes credit card processing fees, amortization of capitalized internal-use software development costs, and allocated overhead costs.

We intend to continue to invest additional resources in our infrastructure and related personnel, and our customer support organization, to support the growth of our business. Some of these investments, including costs of infrastructure equipment (including related depreciation) and expansion, are incurred in advance of generating revenue, and either the failure to generate anticipated revenue or fluctuations in the timing of revenue could affect our gross margin from period to period.

Operating Expenses

The most significant components of our operating expenses are personnel costs, which consist of salaries, benefits, bonuses, and stock-based compensation. We also incur other non-personnel costs related to our general overhead expenses. We expect that our operating expenses will increase in absolute dollars as we grow our business.

Research and Development

Research and development expenses consist primarily of our investment in personnel costs, consultant fees, costs related to technical operations, subscription services for use by our research and development organization and an allocation of our general overhead expenses. We capitalize the portion of our software development costs that meets the criteria for capitalization.

We expect our investment in research and development to increase in absolute dollars for the foreseeable future as we continue to focus our research and development investments on adding new features to our platform, improving our cloud service offerings, and increasing the functionality of our existing features. Our research and development expenses may fluctuate as a percentage of total revenue from period to period due to the timing and extent of these expenses.

Sales and Marketing

Sales and marketing expenses consist primarily of our investment in personnel costs. Sales and marketing also include investments related to advertising, marketing, our brand awareness activities, commissions paid to marketing partners, and an allocation of our general overhead expenses.

We plan to continue investing in sales and marketing by increasing our sales and marketing headcount, supplementing our self-serve model with a direct sales approach, expanding our partner ecosystem, driving our go-to-market strategies, building our lead generation and brand awareness, and sponsoring additional marketing events. As a result, we expect our investment in sales and marketing to increase in absolute dollars for the foreseeable future. Sales and marketing expenses may fluctuate as a percentage of total revenue from period to period because of the timing and extent of these expenses.

General and Administrative

General and administrative expenses consist primarily of personnel costs for our accounting, finance, legal, IT, security, human resources, and administrative support personnel and executives. General and administrative expenses also include costs related to legal and other professional services fees, sales and other taxes; depreciation and amortization; and an allocation of our general overhead expenses. We expect our general and administrative expenses to increase in absolute dollars as our business grows. We expect to continue incurring general and administrative expenses as a result of operating as a public company, including expenses for insurance, costs to comply with the rules and regulations applicable to

28

companies listed on a national securities exchange, costs related to compliance and reporting obligations pursuant to the rules and regulations of the SEC, investor relations, and professional services expenses.

Investment Income

Investment income consists primarily of interest earned on our cash balances and investments.

Interest Expense

Interest expense consists primarily of interest related to our finance lease agreements and interest on the outstanding balance of our existing credit facility.

Income Tax Benefit

Provision for income taxes consists primarily of income taxes in certain foreign and state jurisdictions in which we conduct business. We maintain a full valuation allowance against our U.S. deferred tax assets because we have concluded that it is more likely than not that our deferred tax assets will not be realized.

________________

(1) For the periods presented, Physical Media revenue has been consolidated into B2 Cloud Storage or Computer Backup revenue based on the underlying offering from which it originates.

Total revenue increased by $3.2 million, or 15%, for the three months ended September 30, 2023 compared to the same period in 2022. B2 Cloud Storage increased by $2.7 million, approximately half of which was due to increased storage for existing customers, supplemented by the addition of new customers and sales from B2 Reserve in equal amounts. The remaining increase of $0.5 million was from Computer Backup, a majority of which was due to a prior price increase that began to take effect in September 2021, and a lesser impact due to the addition of new customers and an increase in the number of licenses per existing customer.

Total revenue increased by $11.1 million, or 18%, for the nine months ended September 30, 2023 compared to the same period in 2022. B2 Cloud Storage increased by $8.7 million, approximately half of which was due to increased storage for existing customers, supplemented by the addition of new customers and sales from B2 reserve in equal amounts. The remaining increase of $2.3 million was from Computer Backup, a majority of which was due to a prior price increase that began to take effect in September 2021, and a lesser impact due to the addition of new customers and an increase in the number of licenses per existing customer.

During the third quarter of 2023, we announced pricing increases across our Computer Backup and B2 Cloud Storage products, which became effective October 3, 2023. While the impact of these price increases have inherent uncertainty, we expect a favorable impact to total revenue across our products over the next 12 months, and do not expect a significant change in costs solely as a result of the increase.

Gross margin	46		%	51		%					47		%	52		%

Cost of revenue increased by $2.7 million, or 25%, for the three months ended September 30, 2023 compared to the same period in 2022. The increase was primarily attributable to $1.5 million related to managing and operating our co-location facilities that included new data centers and $1.2 million in depreciation of our infrastructure equipment, which resulted from purchasing additional hard drives and related infrastructure in order to support the growth of our business.

Cost of revenue increased by $8.4 million, or 28%, for the nine months ended September 30, 2023 compared to the same period in 2022. The increase was primarily attributable to $4.7 million related to managing and operating our co-location facilities that included new data centers and the expansion of an existing data center and $3.7 million in depreciation of our infrastructure equipment, which resulted from purchasing additional hard drives and related infrastructure in order to support the growth of our business.

Gross margin was 46% for the three months ended September 30, 2023 compared to 51% for the same period in 2022. The decrease in gross margin was primarily due to cost of revenue increasing at a higher rate as compared to our total revenue growth as a result of opening of new data centers and purchase of additional infrastructure equipment in order to support the growth of our business.

Gross margin was 47% for the nine months ended September 30, 2023 compared to 52% for the same period in 2022. The decrease in gross margin was primarily due to cost of revenue increasing at a higher rate as compared to our total revenue growth as a result of the opening and expansion of data centers and purchase of additional infrastructure equipment in order to support the growth of our business.

While the impact of the price increase we announced during the third quarter of 2023 has inherent uncertainty, we expect a favorable impact to gross margin over the next 12 months as we do not expect a significant change in costs solely as a result of the increase. Further, we plan to purchase additional infrastructure equipment of a similar magnitude over the next 12 months in order to support the growth of our business.

Non-GAAP Financial Measures

To supplement our financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States, or GAAP, we provide investors with non-GAAP financial measures including adjusted gross margin and adjusted EBITDA, each as defined below. These measures are presented for supplemental informational purposes only, have limitations as analytical tools and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of these measures as tools for comparison. Because of these limitations, when evaluating our performance, you should consider each of these non-GAAP financial measures alongside other financial performance measures, including the most directly comparable financial measure calculated in accordance with GAAP and our other GAAP results. A reconciliation of each of our non-GAAP financial measures to the most directly comparable financial measure calculated in accordance with GAAP is set forth below.

Adjusted Gross Margin

We believe adjusted gross margin, when taken together with our GAAP financial results, provides a meaningful assessment of our performance, and is useful to us for evaluating our ongoing operations and for internal planning and forecasting purposes.

We define adjusted gross margin as gross profit, excluding stock-based compensation expense, depreciation and amortization within cost of revenue, as a percentage of adjusted gross profit to revenue. We exclude stock-based compensation, which is a non-cash item, because we do not consider it indicative of our core operating performance. We exclude depreciation expense of our property and equipment and amortization expense of capitalized internal-use software, because these may not reflect current or future cash spending levels to support our business. We believe adjusted gross margin provides consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as this metric eliminates the effects of depreciation and amortization.

The following table presents a reconciliation of gross margin, the most directly comparable financial measure stated in accordance with GAAP, to adjusted gross margin, for each of the periods presented:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022

Adjusted gross profit	$	18,742		$	16,699		$	54,120		$	47,311
Gross margin	46		%	51		%	47		%	52		%
Adjusted gross margin	74		%	76		%	74		%	76		%

33

Adjusted EBITDA

Our management uses adjusted EBITDA to assess our operating performance. We define adjusted EBITDA as net loss adjusted to exclude depreciation and amortization, stock-based compensation, interest expense, investment income, income tax provision, workforce reduction and related severance charges, and other non-recurring charges. We use adjusted EBITDA to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that adjusted EBITDA, when taken together with our GAAP financial results, provides meaningful supplemental information regarding our operating performance by excluding certain items that may not be indicative of our business, results of operations or outlook. We consider adjusted EBITDA to be an important measure because it helps illustrate underlying trends in our business and our historical operating performance on a more consistent basis. We define adjusted EBITDA margin as adjusted EBITDA as a percentage of total revenue.

Our calculation of adjusted EBITDA may differ from the calculations of adjusted EBITDA by other companies and therefore comparability may be limited. Because of these limitations, when evaluating our performance, you should consider adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results. The following table presents a reconciliation of net loss, the most directly comparable financial measure stated in accordance with GAAP, to adjusted EBITDA for each of the periods presented.

See Note 15 to our financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information regarding restructuring charges.

Liquidity and Capital Resources

Since inception, we have financed operations primarily through payments received from our customers and, in later periods from the net proceeds from our IPO. As of September 30, 2023 and December 31, 2022, our principal sources of liquidity were cash, short-term investments and restricted cash, current and restricted cash, non-current of $35.8 million and $69.7 million, respectively. In general, the Company’s restricted cash may only be used to pay down its credit facility.

We believe that our existing cash, cash equivalents, and short-term investments, together with cash provided by operations and our revolving credit facility, will be sufficient to support our working capital and capital expenditure requirements for at least the next 12 months. Our material cash requirements include contractual and other obligations under our credit facility, finance and operating lease agreements, and purchase commitments as discussed below. Our future capital requirements will depend on many factors, including our total revenue growth rate, the timing and the amount of cash received from customers, the expansion of sales and marketing activities, the timing and extent of spending to support

34

development efforts, the price at which we are able to purchase or lease infrastructure equipment, the introduction of platform enhancements, and the continuing market adoption of our platform. In the future, we may enter into arrangements to acquire or invest in complementary businesses, products, and technologies. We plan to enter into finance lease agreements for purchase of infrastructure equipment and may also be required or choose to seek additional equity or debt financing in addition to our existing credit facility. In the event that we require additional financing, we may not be able to raise such financing on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued innovation, we may not be able to compete successfully, which would harm our business, results of operations, and financial condition.

In October 2021, we entered into a revolving credit agreement (as amended to date, the “RCA”) with City National Bank (the “Lender”). Under the RCA, as amended in April 2022, among other things, (i) amounts available to be borrowed are $30.0 million and (ii) advances on the line of credit will bear interest at a variable rate equal to, at our discretion, (a) the average Secured Overnight Financing Rate (“SOFR”) plus 2.0%, or (b) the base rate. The base rate under the RCA is a rate equal to the greater of (i) 3.00% or (ii) the prime rate most recently announced by the Lender. The RCA matures in September 2024. Currently, the RCA does not have financial covenants and it requires us to hold collateral in the form of a lien prior to any advance. We may plan to refinance this credit facility and may not be able to do so on terms acceptable to us or at all. Any such impact could have a material adverse effect upon our liquidity and business. Due to the banking failures starting in March of 2023, we have seen an adverse change for securing acceptable terms due to heightened uncertainty and risk aversion in the financial sector.

We use City National Bank, a subsidiary of RBC, for our banking needs. In the event of a failure of any financial institutions where we maintain deposits, we may lose timely access to our funds at such institutions and incur significant losses to the extent our funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. In addition, the disruption and uncertainty impacting the banking industry from recent failures of certain banks may result in reduced access to capital, increased costs of capital, and reduced opportunities to invest with investment grade securities, which could also lower investment yields and investment income. Any such impact could have a material adverse effect upon our liquidity and business.

As of September 30, 2023, the outstanding balance under the RCA was $6.1 million, and the amount available to us for borrowing was $23.9 million. The outstanding balance is collateralized by an equal amount of cash held, which we are obligated to hold as restricted cash. For further details, see Note 11 to our financial statements included elsewhere in this Quarterly Report on Form 10-Q.

We generally enter into finance lease arrangements to obtain hard drives and related equipment for our data center operations. We also generally enter into leases for our facilities for data centers and office space under non-cancelable operating leases with various expiration dates. As of September 30, 2023, our future minimum commitments for these finance leases and lease financing obligations including interest were approximately $6.4 million for the remainder of 2023, and $19.1 million for the year ending December 31, 2024. The weighted average discount rate for finance leases was 10.8% as of September 30, 2023. As of September 30, 2023, our future minimum commitments for operating leases, which include both lease and non-lease components, were approximately $1.9 million for the remainder of 2023 and $6.7 million for the year ending December 31, 2024. For further information and our future minimum commitments on our finance leases and operating leases, see Note 10 to our financial statements included elsewhere in this Quarterly Report on Form 10-Q.

In addition, we have purchase commitments that relate mainly to infrastructure agreements used to facilitate our operations. As of September 30, 2023, we had non-cancelable purchase commitments of $2.5 million and $0.7 million payable during the remainder of the year ending December 31, 2023 and the year ending December 31, 2024, respectively.

The following table shows a summary of our cash flows for the periods presented:

	Nine Months Ended September 30,
	2023		2022

Operating Activities

Our largest source of operating cash is payments received from our customers. Our primary uses of cash from operating activities are for personnel-related expenses, sales and marketing expenses, infrastructure expenses, and overhead expenses.

Cash used in operating activities primarily consists of our net loss adjusted for certain non-cash items, including stock-based compensation, depreciation, and amortization of property and equipment, net, amortization of capitalized internal-use software, net, and changes in operating assets and liabilities during each period.

For the nine months ended September 30, 2023, cash used in operating activities was $10.6 million, which resulted from a net loss of $47.5 million, adjusted for non-cash charges of $38.7 million and net cash outflow of $1.8 million from changes in operating assets and liabilities. Non-cash charges primarily consisted of $18.3 million for depreciation and amortization expense and $18.7 million for stock-based compensation expense. The net cash outflow from changes in operating assets and liabilities was primarily the result of a $2.0 million decrease of operating lease liabilities, a $1.1 million increase in accounts receivable, a $0.6 million decrease in accounts payable and a $0.4 million decrease in accrued expenses and other current liabilities, which decreased primarily due to our accrued compensation and due to timing of payment of our expenses, offset in part by a $1.7 million increase of deferred revenue, which increased due to our growing customer base and timing of collections from our customers and a $0.9 million decrease in prepaid and other current assets. Cash used in operations was relatively flat for the nine months ended September 30, 2023, as compared to the same period in 2022 as our increase in net loss was comprised of non-cash charges of stock-based compensation expense and depreciation and amortization expense, partially offset by an increase in deferred revenue.

For the nine months ended September 30, 2022, cash used in operating activities was $10.6 million, which resulted from a net loss of $36.9 million, adjusted for non-cash charges of $29.2 million and net cash outflow of $2.9 million from changes in operating assets and liabilities. Non-cash charges primarily consisted of $14.7 million for depreciation and amortization expense and $13.0 million for stock-based compensation expense. The net cash outflow from changes in operating assets and liabilities was primarily the result of a $1.9 million decrease of operating lease liabilities, $0.9 million decrease in accrued expenses and other current liabilities, which decreased primarily due to our ESPP withholdings and due to timing of payment of our expenses, and $0.2 million increase of prepaid and other current assets, offset in part by a $0.6 million increase of deferred revenue, which increased due to our growing customer base and timing of collections from our customers.

Investing Activities

Cash provided by investing activities during the nine months ended September 30, 2023 was $22.1 million, resulting primarily from the $57.4 million maturity of our short-term investments and $0.3 million from the disposition of certain hard drives, offset in part by the purchase of short-term maturity investments of $19.5 million, $11.1 million related to the development of internal-use software for adding new features and enhanced functionality to our platform, and capital expenditures of $5.1 million in support of infrastructure deployments to support our growing business.

Cash used in investing activities during the nine months ended September 30, 2022 was $62.0 million, resulting primarily from the purchase of short-term maturity investments of $113.3 million, capital expenditures of $4.1 million in support of infrastructure deployments to support our growing business, and $5.6 million related to the development of internal-use software for adding new features and enhanced functionality to our platform, offset in part by $61.0 million from the maturity of our short-term investments.

Financing Activities

Cash used in financing activities for the nine months ended September 30, 2023 was $7.6 million. Cash used in financing activities was primarily due to principal payments on our finance lease agreements and lease financing obligations of $14.9 million related to hard drives and other infrastructure equipment used in our co-location facilities, $2.5 million of repayment of principal on our line of credit and $1.5 million related to repayment of principal on financed insurance premiums, offset in part by $4.3 million in proceeds from our credit facility, $3.4 million in proceeds from the exercise of employee stock options, $2.5 million from our lease financing transaction and $1.2 million in proceeds from our ESPP.

Cash used in financing activities for the nine months ended September 30, 2022 was $4.9 million. Cash used in financing activities was primarily due to principal payments on our finance lease agreements and lease financing obligations of

36

$11.6 million related to hard drives and other infrastructure equipment used in our co-location facilities and $0.7 million related to payments made for offering costs that are deferred, offset in part by $3.4 million in proceeds from the exercise of employee stock options, $2.5 million in proceeds from our credit facility, and $1.5 million in proceeds from our ESPP.

Critical Accounting Policies and Estimates

Our financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q are prepared in accordance with GAAP. The preparation of condensed consolidated financial statements also requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from the estimates made by management. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations, and cash flows will be affected.

There have been no material changes to our critical accounting policies and estimates as compared to those discussed in the Annual Report on Form 10-K, except as described in “Note 2” to the financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Recently Adopted Accounting Pronouncements

See Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in the notes to our condensed consolidated financial statements included in this Quarterly Report for a discussion of recent accounting pronouncements.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the Jumpstart Our Business Startups (JOBS) Act. For so long as we continue to be an emerging growth company, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation. The JOBS Act also provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards applicable to public companies. This provision allows an emerging growth company to delay the adoption of some accounting standards unless and until those standards would otherwise apply to private companies. We have elected to use the extended transition period under the JOBS Act for the adoption of accounting standards until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign currency exchange rates.

Interest Rate Risk

Our exposure to interest rate risk primarily relates to our finance lease arrangements and lease financing obligations for obtaining hard drives and related equipment for our data center operations, which may be impacted by interest rate changes for any future agreements we enter in to, and our credit facility with City National Bank. We also earn interest income generated by cash, cash equivalents and short-term investments held at City National Bank. As of September 30, 2023, we had cash and cash equivalents and short-term investments balances of $9.0 million and $20.7 million, respectively. Interest-earning instruments carry a degree of interest rate risk. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. As such, we generally do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate risk exposure, and intend to hold all investments to their respective maturities. Due to the short-term nature of

37

these investments and as all investments are generally intended to be held-to-maturity, we do not believe that an increase or decrease in interest rates of 100 basis points would have a material effect on our operating results or financial condition.

Further, our credit facility with City National Bank, which was initially entered into during October 2021, as amended, is at a variable interest rate tied, at our discretion, to SOFR or to the Prime Rate most recently announced by City National Bank, assuming such rate is greater than 3.0%.

Foreign Currency Exchange Rate Risk

Our reporting currency and the functional currency of our wholly owned foreign subsidiaries is the U.S. dollar. Our sales are currently denominated in the U.S. dollar and we have minimal foreign currency risk related to our revenue. In addition, most of our operating expenses are denominated in the U.S. dollar, resulting in minimal foreign currency risks. The volatility of exchange rates depends on many factors that we cannot accurately forecast. In the future, if our international sales increase or more of our expenses are denominated in currencies other than the U.S. dollar, our operating results may be adversely affected by fluctuations in the exchange rates of the currencies in which we do business. At this time we do not, but we may in the future, enter into derivatives or other financial instruments in an attempt to hedge our foreign currency exchange risk. It is difficult to predict the impact hedging activities could have on our results of operations.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission (“SEC”) rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were not effective over certain financial reporting areas due to the material weaknesses in our internal control over financial reporting described below. In light of this fact, our management has performed additional analyses, reconciliations, and other post-closing procedures and has concluded that, notwithstanding the material weaknesses in our internal control over financial reporting, the condensed consolidated financial statements for the periods covered by and included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with GAAP.

Material Weaknesses

As disclosed in the section titled “Risk Factors” in Part II, Item 1A of this Quarterly Report on Form 10-Q, we previously identified control deficiencies in the design and implementation of our internal control over financial reporting that constituted material weaknesses. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis.

The three outstanding material weaknesses identified in our internal control over financial reporting related to (i) a lack of sufficient and timely review of significant accounting transactions and reconciliations, (ii) inadequate ability to timely identify errors related to the recording of certain equity transactions, and (iii) the design and operating effectiveness of controls over our going concern assessment, which was identified during the quarter ended September 30, 2023.

Remediation Plans

We have dedicated significant effort and resources towards measures to remediate the identified material weaknesses. We have designed and implemented controls to address certain material weaknesses and are testing our controls through our monitoring programs. The material weaknesses cannot be considered fully remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

38

These specific efforts include: (1) strengthening our internal controls over financial reporting and the design of our internal-control framework through enhanced accounting policies, control activities, and monitoring; (2) enhancing the precision of control around balance sheets reconciliation review controls, including the review of underlying source data and procedures to strengthen the retention of contemporaneous documentation of control reviews; (3) implementing a new enterprise resource planning (“ERP”) system, additional financial modules to support reconciliations, and other systems and processes related to fixed assets, leases, revenue recognition, and equity administration to increase capabilities over our financial statement recording and reporting processes; (4) hiring additional full-time accounting personnel with appropriate levels of experience to increase our accounting and technical expertise, including a new Chief Financial Officer, a Corporate Controller, an Internal Controls Manager, a Tax Manager, a Director of IT, and additional accounting staff, all with public company experience and / or a Certified Public Accountant certification; and (5) reallocating responsibilities across our accounting organization so that the appropriate level of knowledge and experience is applied based on complexity of transactions, in addition to implementation of sufficient and timely review of significant accounting transactions and reconciliations. We intend to continue to take steps to remediate the material weaknesses described above, design and implement additional controls, and further evolve our accounting processes. We believe the actions described above, which we began implementing in the first quarter of fiscal year 2023, once fully implemented and tested, will be sufficient to remediate the identified material weaknesses and strengthen our internal controls.

For the following material weaknesses in particular, we are documenting specific remediation steps and will continue to work toward demonstrating operating effectiveness for a sufficient period of time. Once operating effectiveness has been demonstrated for a sufficient period of time, we expect all three of our outstanding material weaknesses to be fully remediated:

i.our controls were not operating effectively to allow sufficient and timely review of significant accounting transactions, reconciliations, and presentation of our statement of cash flows. These deficiencies resulted in errors in cash and cash equivalents, prepaid expenses and other current assets, property and equipment, capitalized internal-use software, lease liability and sale leaseback transactions, accrued compensation and income tax;

ii.our controls over certain equity transactions were not operating effectively to allow management to timely identify errors related to the recording of those transactions; specifically, we did not have sufficient technical resources to appropriately identify errors in the accounting for equity awards and preferred stock transactions, resulting in misstatements relating to completeness and accuracy of stock-based compensation and classification of equity instruments; and

iii.our controls were not adequately designed and operating effectively to allow sufficient and timely review of our going concern assessment. Within the going concern assessment, this resulted in incorrect assumptions used in the forecasted cash flows and computational errors.

The actions we are taking are subject to ongoing executive management review and are also subject to audit committee oversight. If we are unable to successfully remediate these material weaknesses, or if in the future, we identify further material weaknesses in our internal control over financial reporting, we may not detect errors on a timely basis and our condensed consolidated financial statements may be materially misstated.

Changes in Internal Control over Financial Reporting

We are taking actions to remediate the material weaknesses relating to our internal control over financial reporting, as described above. Except as otherwise described herein, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended September 30, 2023 covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

39

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

40

Part II - Other Information

ITEM 1. LEGAL PROCEEDINGS

From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that we believe are likely to have a material adverse effect on our business, financial condition, or operating results. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

ITEM 1A. RISK FACTORS

Certain factors may have a material adverse effect on our business, financial condition, and results of operations. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Quarterly Report on Form 10-Q, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our condensed consolidated financial statements and the accompanying notes, included elsewhere in this Quarterly Report on Form 10-Q. Our business, financial condition, results of operations, or prospects could also be harmed by risks and uncertainties not currently known to us or that we currently do not believe are material. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity, results of operations, and the market price of our Class A Common Stock.

Risk Factors Summary

Below is a summary of the principal factors that make an investment in our Class A common stock speculative or risky. Importantly, this summary does not address all of the risks that we face. Our ability to execute our business strategy is subject to numerous risks, as more fully described in the section titled “Risk Factors” immediately following this summary. These risks include, among others:

• We have a history of cumulative losses, and we do not expect to be profitable for the foreseeable future.

• The markets in which we participate are intensely competitive, and if we do not compete effectively, our operating results would be harmed.

• Any significant disruption in our service or loss, or delay in availability, of our customers’ data, could damage our reputation and harm our business and operating results.

• If we are unable to maintain our brand and reputation, our business, results of operations, and financial condition may be adversely affected.

• If our information technology systems, including the data of our customers stored in our systems, are breached or subject to cybersecurity attacks, our reputation and business may be harmed.

• If we are unable to attract and retain customers on a cost-effective basis, our revenue and operating results would be adversely affected.

• If we are unable to provide successful enhancements, new features, and modifications to our cloud services, our business could be adversely affected.

• Material defects or errors in our software could negatively impact our business, harm our reputation, result in significant costs to us, and negatively impact our ability to sell our cloud services.

• We rely on third-party vendors and suppliers, including data center and hard drive providers, which may have limited sources of supply, and this reliance exposes us to potential supply and service disruptions that could harm our business.

• Our business depends, in part, on the success of our strategic relationships with third parties.

• We have identified material weaknesses in our internal controls over financial reporting, and the failure to achieve and maintain effective internal controls over financial reporting could harm our business and negatively impact the value of our Class A common stock.

41

Risks Related to Our Business and Our Industry

We have a history of cumulative losses, and we do not expect to be profitable for the foreseeable future.

We incurred net losses of $47.5 million and $36.9 million for the nine months ended September 30, 2023 and 2022, respectively. Over our 15 years of operations, we had an accumulated deficit of $135.2 million as of September 30, 2023. We cannot guarantee that net losses in future periods will be similar to those from prior periods. We intend to continue scaling our business to increase our customer base and to meet the increasingly complex needs of our customers. We have invested, and expect to continue to invest, in our sales and marketing organization to sell our cloud services around the world and in our development organization to deliver additional features and capabilities of our cloud services to address our customers’ evolving needs. We also expect to continue to make significant investments in our data center infrastructure and technical operations organization as we further scale our business. As a result of our continuing investments to scale our business in each of these areas, we do not expect to be profitable for the foreseeable future. We cannot assure you that we will achieve profitability in the future or that, if we do become profitable, we will sustain profitability.

The markets in which we participate are intensely competitive, and if we do not compete effectively, our operating results would be harmed.

The markets in which we operate are highly competitive, with relatively low barriers to entry for certain applications and services. Some of our competitors include cloud-based services such as those offered by Amazon.com, Inc. through Amazon Web Services, Alphabet Inc. through Google Cloud Platform, and Microsoft Corporation through Azure, and on-premises offerings such as those offered by EMC/Dell and NetApp. Many of our competitors and potential competitors are larger and have greater name and brand recognition; much longer operating histories; larger marketing budgets for the development, promotion and sale of their products or services; broader service offerings and capabilities; and significantly greater resources than we do. In addition, many of our competitors have established marketing and distribution relationships with channel partners, consultants, system integrators, and resellers. Our competitors may also be able to respond more quickly and effectively to new or changing opportunities, technologies, standards, or customer requirements. Competition may intensify in the future and may also include new market entrants, including storage offerings by some of our partners. Our competitors could offer their products or services at a lower price or in some combination with other services or applications that we do not offer, which could result in pricing pressures on our business. We also recently announced price increases to our Computer Backup and B2 Cloud Storage offerings, which could cause us to lose existing customers who do not wish to renew their subscriptions at the higher prices, reduce the number of new customers that buy our products, or decrease the amount of data that customers store with us. Increased competition generally could result in reduced sales, increased customer churn, lower margins, losses, or the failure of our cloud services to achieve or maintain widespread market acceptance, any of which could harm our business.

Any significant disruption in our service or loss, or delay in availability of our customers’ data, could damage our reputation and harm our business and operating results.

Our brand, reputation, and ability to manage our systems; attract, retain, and serve our customers; and interface with our partners, are dependent upon the reliable performance of our platform, including our underlying technical infrastructure, as well as the systems and infrastructure of various third parties, including third-party hosted data centers that we use and internet access and infrastructure used by us and our customers and partners. Our customers rely on our platform to store and access their data, including financial records, business information, personal information, documents, media, and other important content. There are various reasons that our platform, or the systems that are used to access or support our platform, could experience a disruption in service, some of which are entirely outside of our control. For example, our facilities as well as the data centers that we use are vulnerable to damage or interruption from human error, intentional bad acts, extreme weather, earthquakes, floods, fires, war or other military conflict, including the conflicts between Russia-Ukraine and Israel-Hamas, which may further escalate and could directly or indirectly involve other countries, including the United States, terrorist attacks, cybersecurity attacks or the risk of potential cybersecurity attacks, power losses, hardware failures, systems failures, telecommunications failures, and similar events, any of which could disrupt our service, destroy user content, or prevent us from being able to continuously back up or record changes in our users’ content. For example, a third party vendor that operated one of our multiple data center locations, filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code in 2022. This bankruptcy matter was resolved without disruption to our normal operations, but future bankruptcies or similar events affecting our third-party hosted data center providers could result in disruptions to our Company, access to customer data may become unavailable or customer data could be lost, and it may take a significant period of time to achieve full resumption of our cloud services. Also, in response to the Russian attack on Ukraine that began in February 2022, the United States and many other countries began imposing sanctions on Russia and certain parts of Ukraine, including restrictions on the import and export of goods and services to those regions. These restrictions have also been expanded to other countries, including Belarus. Although we do not have a

42

significant number of customers located in those regions, such actions will have some impact on our business. It is difficult to predict how long the conflict may last, how the conflict could escalate, and how the sanctions may evolve, which could cause a greater adverse impact on our business and operations. Our disaster recovery planning cannot account for all eventualities and even if we anticipate an incident, our disaster recovery plans may not be sufficient to timely and effectively address the issue. Moreover, our platform and technical infrastructure may not be adequately designed with sufficient reliability and redundancy to avoid delays or outages that could be harmful to our business. If our platform is unavailable when users attempt to access it, or if it does not load as quickly as they expect, or if data is lost, users may not use our platform as often in the future, or at all.

If we are unable to maintain our brand and reputation, our business, results of operations, and financial condition may be adversely affected.

The successful promotion of our brand and our ability to maintain our reputation will depend on a number of factors, including our performance and the reliability of our cloud services; our advertising and marketing efforts, including our blog and social media presence, which have been important to building and maintaining our brand and reputation; our ability to continue to develop high-quality features and cloud services; and our ability to successfully differentiate our cloud services from competitive products and services. Our brand promotion activities may not be successful or yield increased revenue.

The promotion of our brand may require us to make substantial expenditures, particularly as our markets become more competitive and we expand into new markets or offer new products or services, or additional features. Expenditures intended to maintain and enhance our brand may not be cost-effective or effective at all. If we do not successfully maintain and enhance our brand, we may have reduced pricing power relative to our competitors, we could lose customers, we could fail to attract potential new customers or retain our existing customers, or our blog and thought leadership in our industry may decline in popularity, all of which could materially and adversely affect our business.

If our information technology systems, including the data of our customers stored in our systems, are breached or subject to cybersecurity attacks, our reputation and business may be harmed.

Our customers rely on our solutions to store their files, which may include confidential or personally identifiable information, critical business information, photos, and other meaningful content. To manage and maintain such data, we are highly dependent on internal and external information technology systems and infrastructure, including the internet, to securely process, transmit, and store critical information. Although we take measures to protect our systems and sensitive information from unauthorized access or disclosure, third parties may be able to circumvent our security by deploying viruses, worms, and other malicious software programs that are designed to attack or attempt to infiltrate our systems and networks, including distributed denial of service (DDoS) or phishing attacks, that can undermine the availability and performance of our systems and cloud services, resulting in the blocking of our services by ISPs or governments, fraudulently steal data, or otherwise cause damage to our reputation. For example, in December 2021, an industry-wide zero-day vulnerability was discovered in the Apache Log4j logging library commonly used by many companies throughout the world that could enable attackers to take control of vulnerable servers. Although we were not aware of any unauthorized access to our systems due to the Log4j vulnerability, out of an abundance of caution and because Log4j was leveraged widely in our environment, we decided it was in our customers’ best interest to take our systems offline for a short period of time until we could apply the security patch. In addition, we regularly encounter attempts to create false or undesirable user accounts, which can disrupt our systems, impair system performance and impact analytics. Moreover, cybersecurity attacks evolve rapidly and may utilize new methods not recognized. We may be unable to successfully identify, stop, or resolve such attacks, or implement adequate preventative measures and incur costs in our efforts to protect against and respond to cyber-attacks and potential cyber-attacks. Also, the use of generative artificial intelligence, or other societal or political developments, could result in a greater likelihood of cybersecurity incidents that could either directly or indirectly impact our operations. In addition, employee or consultant error, malfeasance, or other errors in the storage, use, or transmission of customer data could result in a breach. For example, in late March 2021, it was discovered that a Backblaze marketing campaign leveraging the Facebook ad network, which had been launched two weeks earlier, had been incorrectly configured to run on all Backblaze platform pages instead of only the Backblaze marketing pages as intended. Once we became aware of the issue, it was promptly resolved. Although we believe that less than 2% of Backblaze customers may have been affected, and no actual customer files, file contents, or user account information were shared at any time, certain file metadata may have been inadvertently shared with Facebook. Even if a breach is detected, the full extent of the breach may not be determined immediately, or at all. While we maintain insurance coverage to mitigate the potential financial impact of these risks, our insurance may not cover all such events or may be insufficient to compensate us for potentially significant losses, including the potential damage to the future growth of our business, that may result from any such breach. In addition, our business utilizes information technology systems of our partners and vendors, who

43

are also subject to similar cybersecurity risks that could adversely impact the security of our systems and business. We may have little or no control over how cybersecurity attacks on our partners or vendors are addressed. An actual or perceived breach of our network security and systems or other cybersecurity-related events that cause the loss, theft or unauthorized disclosure of our customers’ information, including any delay in determining the full extent of a potential breach, could have a material adverse impact on our business, results of operations, and financial condition, including harm to our reputation and brand, reduced demand for our solutions, time-consuming and expensive litigation, fines, penalties, and other damages.

If we are unable to attract and retain customers on a cost-effective basis, our revenue and operating results would be adversely affected.

We generate substantially all of our revenue from the sale of our cloud services either on a consumption or subscription model. To grow, we must continue to attract a large number of customers on a cost-effective basis. Our recent price increase for Computer Backup and B2 Cloud Storage could make it more difficult to attract new customers and retain existing customers, or cause existing customers to reduce the amount of data that they store with us, thus negatively impacting our revenue and business. We have historically used, and plan to increase our use of, a variety of advertising and marketing programs to promote our cloud services. Our sales and marketing investments intended to accelerate the scaling of our business including any expansion of existing programs and new programs to promote our cloud services, may not be successful or provide a reasonable return on investment within a desired timeframe. Significant increases in the pricing of one or more of our advertising channels would increase our advertising and marketing costs or cause us to choose less expensive and perhaps less effective channels. We may also need to expand into channels with significantly higher costs, which could adversely affect our operating results. We may also incur advertising and marketing expenses significantly in advance of the time we anticipate recognizing any revenue generated by such expenses, and we may only at a later date, or never, experience an increase in revenue or brand awareness as a result of such expenditures. If we are unable to maintain effective advertising and marketing programs, our ability to attract new customers could be adversely affected, our advertising and marketing expenses could increase substantially, and our operating results may suffer.

A portion of our potential customers locate our website through search engines, such as Google, Bing, and Yahoo!. Our ability to maintain the number of visitors directed to our website is not entirely within our control. If search engine companies modify their search algorithms in a manner that reduces the prominence of our listing, or if our competitors’ search engine optimization efforts are more successful than ours, fewer potential customers may click through to our website. In addition, the cost of purchased listings has increased in the past and may increase in the future. A decrease in website traffic or an increase in promoted search result costs could adversely affect our customer acquisition efforts and our operating results. In addition, we also rely on our blog and word of mouth to drive additional customers. To the extent our blog does not continue to attract readers or if our reputation is harmed, these additional means of attracting customers may no longer provide significant numbers of customers in the future.

In addition, because we offer our Computer Backup cloud service at a fixed price, the amount of data our customers back up affects our costs and gross margins. Subject to certain limitations, we also offer free egress for our B2 Cloud Storage customers. To the extent current or future customers back up unusually large amounts of data, use an excessive amount of egress or growth in the amount of data backed up per customer outpaces decreases in storage costs, our costs, gross margins and infrastructure could be adversely affected.

If we are unable to provide successful enhancements, new features, and modifications to our cloud services, our business could be adversely affected.

Our industry is marked by rapid technological developments and new and enhanced applications and cloud services. If we are unable to provide enhancements and new features for our existing services or new services that achieve market acceptance or that keep pace with rapid technological developments, our business could be adversely affected. In addition, because our cloud services are designed to operate on a variety of systems, we will need to continuously modify and enhance our cloud services to keep pace with changes in internet-related hardware, operating systems, and other software, communication, browser, and database technologies, including the systems of our partners, vendors, and competitors. We also have limited internal resources and thus need to selectively prioritize features and other development and infrastructure projects, and de-prioritize other such projects. Although we seek to prioritize the most important projects and de-prioritize projects of lesser importance based on the information available to us at any given time, there is no guarantee that our prioritization efforts will achieve the desired market adoption or infrastructure improvements and we may not be successful in either developing these modifications and enhancements or in bringing them to market in a timely fashion. In addition, any failure of our cloud services to operate effectively and on a timely basis with network platforms and technologies could

44

reduce the demand for our cloud services, result in customer dissatisfaction and adversely affect our business. Furthermore, future enhancements, features or offerings may increase our research and development expenses and infrastructure costs, which could adversely impact our pricing advantage, undermine our ease of use, make it more difficult to attract and retain customers, and harm our results of operations.

Material defects or errors in our software or hardware failures could negatively impact our business, harm our reputation, result in significant costs to us, and negatively impact our ability to sell our cloud services.

The software underlying our cloud services is inherently complex and may contain material defects or errors, particularly when first introduced or when new versions or enhancements are released. We have from time to time found defects or errors in our cloud services, and new defects or errors in our existing solutions may be detected in the future by us, our customers or partners, or other third parties. The costs incurred in correcting such defects or errors may be substantial and could negatively impact our business. Backblaze employees could also introduce defects or errors through incompetence, malfeasance, or a mistake that would lead to data loss. For example, to the extent that the encryption keys for encrypted customer data stored by Backblaze were to be deleted or corrupted, the data could become unrecoverable. In addition, we rely on hardware purchased or leased and software licensed from third parties to offer our cloud services. Hardware is susceptible to failures over time and may require increased maintenance effort and costs. Any defects in, or unavailability of, our software or hardware failures that cause interruptions to the availability of our cloud services or that otherwise impact our business could, among other things:

•require us to issue refunds or credits to our customers or expose us to claims for damages,

•cause us to lose existing customers and make it more difficult to attract new customers,

•divert our development resources or require us to make extensive changes to our cloud services or software,

•harm our reputation and brand, and

•negatively impact our results of operations.

If we fail to effectively manage our growth, our business would be harmed.

We have recently experienced, and continue to experience, a period of rapid growth. For example, our headcount grew from 188 employees as of December 31, 2020, to 270 employees as of December 31, 2021 and to 393 employees as of December 31, 2022. Also, in just the last two years the amount of storage deployed by us has increased significantly. The number of customers and customer requests on our network has also increased rapidly in recent years. Our growth may not be sustainable. In fact, we recently initiated measures to reduce headcount to pursue greater cost efficiency and align strategic initiatives. These measures were substantially completed during the first nine months of 2023. Nevertheless, in the long term, we expect to continue to expand our operations and to increase our headcount, network, and product offerings significantly. Our growth has placed, and future growth will continue to place, a significant strain on our management, corporate culture, quality of our cloud services, and administrative, operational, security, and financial infrastructure. Our headcount needs may also fluctuate on a quarterly and annual basis and we may seek, and have sought by way of the recent restructuring measures, to “right size” our workforce from time to time due to changing business needs and other conditions, and it may be difficult to effectively manage our workforce on a timely basis in response to such changes. It is also important that we successfully leverage our existing employee base and any headcount growth, particularly as our business grows and the corresponding demands on our business increase. Our success will depend in part on our ability to manage this growth effectively, which will require that we, among other things, continue to improve our administrative, operational, financial, and management systems and controls.

Our business depends on our ability to retain and increase revenue from customers, and if we are unable to do so, our revenue and operating results would be adversely affected.

It is important for our business that our customers continue to use, and even increase their use of, our cloud services. Many of our customers can terminate their use of our cloud services at will with little-to-no advance notice. Even though some of our customers enter into longer-term multi-year agreements, they generally have no obligation to renew their subscriptions or increase usage. Due to our varied customer base and lack of long-term customer and usage commitments, it can be difficult to accurately predict our customer retention rate on a quarterly basis or long-term basis. Our customer retention

45

and the amount of data that they store with us may decline or fluctuate as a result of a number of factors, including potential customer dissatisfaction with our cloud services and offerings; pricing plans; our customers’ own business conditions; customer decisions to delete unneeded or redundant data; the perception, whether or not accurate, that competitive products provide better options; changes in our brand or reputation; and overall general economic conditions. Our recent price increase for Computer Backup and B2 Cloud Storage could make it more difficult to attract new customers and retain existing customers, or cause existing customers to reduce the amount of data that they store with us. Our future financial performance also depends in part on our ability to continue to increase revenue from our customers through additional paid products, such as Extended Version History and multi-region selection. Our customers’ decision whether to opt for additional paid products is driven by a number of factors. If our customers do not perceive the value in such additional paid offerings, we may not realize the anticipated benefits of our investments in such additional features, and our financial results could be harmed. If we cannot successfully retain our existing customers and add new customers consistent with historical rates, including maintaining or growing the amount of data that our customers store with us, our revenue and ability to grow may be adversely affected.

To the extent we target different types of customers, we may face increased demands and challenges that adversely impact our business and operations.

Historically, most of our customers consisted of small-to-medium sized businesses and individuals. To the extent we target other types of customers or customers with different needs, we may face greater demand for certain service enhancements or features that we do not currently offer, or additional performance, availability, durability, and security requirements. Certain types of customers may also have longer sales cycles, less predictability or higher volatility in the amount of data they store with us, increased pricing or negotiation leverage, and increased customer education and overall customer engagement needs. In addition, some customers may demand more customization, integration, and support services. Any of these factors could require us to devote greater sales, engineering, marketing, operations, and support services as well as make significant infrastructure changes, which could increase our costs, divert key resources from other current and prospective customers, and otherwise adversely affect our business and operating results. These increased demands and challenges may also be for the benefit of a limited number of customers. Moreover, we cannot assure you that any such efforts will be successful or justify the additional investments in a timely manner, or at all. 

The material stored using our cloud services may subject us to negative publicity, legal liability, and harm our business.

We are not aware of the contents of the data that customers store using our cloud services. While we do have a detailed process to address any third-party complaint regarding illegal or other inappropriate use of our cloud services by a customer that would violate our terms of service, for security and privacy reasons we do not actively monitor the content of data that is being stored with us. To the extent that sensitive, personally identifiable, illegal, or controversial data is stored in our servers and that becomes known publicly, particularly given the highly volatile nature of the political landscape throughout the world and immediate access by individuals to social media platforms with a broad outreach, it may create negative publicity and adversely impact our reputation and harm our business. 

Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.

Our quarterly results of operations may vary significantly in the future. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly results of operations may fluctuate as a result of a variety of factors, many of which are outside of our control, and as a result may not fully reflect the underlying performance of our business. Fluctuation in quarterly results may negatively impact the trading price of our Class A common stock. Factors that may cause fluctuations in our quarterly results of operations include, without limitation:

•our ability to attract new customers;

•the amount of customer churn;

•fluctuations in the amount of data customers store with us;

•the amount and timing of operating expenses and equipment purchases related to the maintenance and expansion of our business;

•interruptions or loss of service of our offerings;

46

•the timing and success of new product feature and service introductions by us or our competitors;

•our ability to retain and increase revenue from customers;

•changes in deferred revenue balances;

•changes in or timing of cash flows;

•changes in the competitive dynamics of our industry, including consolidation among competitors;

•security breaches of our systems;

•our involvement in litigation, or the threat thereof;

•the length of the sales cycle;

•outbreaks of war or other hostilities, such as the Russia-Ukraine and Israel-Hamas hostilities;

•inflation in the United States, which has recently hit a four decade high, and other regions;

•the impact of COVID-19 or other pandemics on our business or that of our customers and partners;

•the timing of expenses and receipt of perceived benefits related to any acquisitions;

•changes in laws and regulations that impact our business; and

•general economic and market conditions.

For example, in addition to the risks from sanctions and other restrictions discussed elsewhere in these Risk Factors in connection with the Russian attack on Ukraine that began in February 2022, in order to help the people of Ukraine facing a humanitarian crisis, while it is subject to change, we are currently waiving charges for our services for customers based in Ukraine. We are also unable to receive payments from customers in certain regions that are subject to banking or other credit card payment restrictions, including Russia and Belarus. Although we do not have a significant amount of customers located in these regions, such actions will have some impact on our business. The Russian-Ukraine conflict has also caused oil prices to rise and increased the risk of disruption to the supply chain for oil, which could result in higher energy costs for our business and data centers, which could negatively impact our results of operations. The hostilities in various places around the world could also escalate further and directly or indirectly involve other countries, including the United States, which could cause a greater impact on us and our customers, partners and supplies.

Further, as we continue to grow and scale our business to meet the needs of our customers, we may overestimate or underestimate our infrastructure capacity requirements, which could adversely affect our results of operations. The costs associated with leasing and maintaining our custom-built infrastructure in co-location facilities and third-party data centers already constitute a significant portion of our capital and operating expenses. We continuously evaluate our short and long-term infrastructure capacity requirements and seek to ensure adequate capacity for new and existing users while minimizing unnecessary excess capacity costs. However, we may not be able to sufficiently predict future demand, or the availability of hardware or infrastructure necessary to support increased demand on a timely basis. If we overestimate the demand for our platform and therefore secure excess infrastructure capacity or equipment, our gross margins could be reduced. If we underestimate our infrastructure capacity requirements or availability of necessary hardware or infrastructure, we may not be able to service the needs of new and existing customers; durability, reliability, and performance could suffer; our costs could rise; and our business could be harmed.

We rely on the performance of key personnel, including our management and other key employees, and the loss of one or more of such personnel, or of a significant number of our team members, could harm our business.

We believe our success has depended, and continues to depend, on the efforts and talents of senior management and other key personnel. Substantially all of our employees, including our senior management, are employed on an at-will basis. We cannot ensure that we will be able to retain the services of any member of our senior management or other key employees,

47

particularly given that some of these employees may hold equity of the Company that is largely vested, or that we would be able to timely replace members of our senior management or other key employees should any of them depart. The loss of one or more members of our senior management or other key employees could harm our business.

The failure to attract and retain additional qualified personnel could prevent us from executing our business strategy.

To execute our business strategy, we must attract and retain highly qualified personnel. Competition for executive officers, software developers, sales personnel, operational personnel, and other key employees in our industry is intense. In particular, we compete with many other companies for software developers with high levels of experience in designing, developing, and managing cloud-based software, as well as for skilled sales and operations professionals. In addition, we believe that the success of our business and corporate culture depends on employing a diverse workforce, and the competition for such personnel is significant. The market for such talented personnel is particularly competitive in the San Francisco Bay Area, where our headquarters is located. Many of the companies with which we compete for experienced personnel have greater resources than we do and can frequently offer such personnel substantially greater compensation than we can offer. If we fail to attract new personnel, including accomplished executive talent, or if we fail to retain and motivate our current personnel, our business would be harmed. In addition, if we are unable to hire new employees on a timely basis or reach productive levels in a short time frame, new growth initiatives and other projects may be delayed or otherwise disrupted, which could cause us to miss our performance goals and negatively impact our business.

Our corporate culture has contributed to our success, and if we cannot maintain this culture as we grow, we could lose the innovation, creativity, and teamwork fostered by our culture, and our business may be harmed.

We have a culture that encourages employees to be open, collaborate, strive to do the right thing, and develop and launch new and innovative solutions, which we believe is essential to attracting customers and partners and serving the best, long-term interests of our company. As our business grows and becomes more complex, and now that we are a public company, it may become more difficult to maintain this cultural emphasis. Any failure to preserve our culture could negatively affect our ability to retain and recruit personnel, which is critical to our growth, and to effectively focus on and pursue our strategies. If we fail to maintain our company culture, our business and competitive position may be harmed.

As we expand our operations outside the United States, we may be subject to increased business, regulatory and economic risks that could impact our results of operations.

In the nine months ended September 30, 2023, we derived approximately 28% of our revenue from customers outside of the United States. We may also expand our international operations, which may include hiring employees, building out technical infrastructure, and opening offices in foreign jurisdictions. Any new markets or countries into which we attempt to market and sell our cloud services may not be receptive. For example, we may be unable to expand further in some markets if we are unable to satisfy various government- and region-specific requirements. In addition, our ability to manage our business and conduct our operations internationally requires considerable management attention and resources and is subject to the particular challenges and complexities of deploying infrastructure internationally and supporting a rapidly growing business in an environment of multiple languages, cultures, customs, legal and regulatory systems, alternative dispute systems, and commercial markets. International expansion has required, and will continue to require, investment of significant funds and other resources. Growth in our international operations will subject us to new risks and may increase risks that we currently face, including risks associated with:

•higher costs of doing business internationally, including increased energy, infrastructure, accounting, travel, and legal compliance costs;

•providing our platform, building out the necessary infrastructure and operating our business across a significant distance, in different languages and among different cultures, including the potential need to modify our platform and features to ensure that they are culturally appropriate and relevant in different countries;

•compliance with applicable international laws and regulations, including laws and regulations with respect to privacy, data protection, consumer protection, and unsolicited email, and the risk of penalties to our users and individual members of management or employees if our practices are deemed to be out of compliance, and additional laws and regulations in the United States that are applicable to international operations;

48

•recruiting and retaining talented and capable employees outside the United States, and maintaining our company culture across all of our offices;

•management of an employee base in jurisdictions that may not give us the same employment and retention flexibility as does the United States;

•operating in jurisdictions that do not protect intellectual property rights to the same extent as does the United States;

•compliance by us and our business partners with anti-corruption laws, anti-bribery, anti-money laundering, and similar laws; import and export control laws; tariffs and trade barriers; economic sanctions; and other regulatory limitations on our ability to provide our cloud services in international markets;

•foreign exchange controls that might require significant lead time in setting up operations in certain geographic territories;

•restrictions that might prevent us from repatriating cash earned outside the United States;

•double taxation of our international earnings and potentially adverse tax consequences due to changes in the income and other tax laws of the United States or the international jurisdictions in which we operate; and

•political and economic instability in various jurisdictions.

Expanding our international operations and complying with applicable laws and regulations may substantially increase our cost of doing business in international jurisdictions. We may also be unable to keep current with changes in laws and regulations as they develop, and we or our employees, contractors, partners, and agents may fail to maintain compliance with applicable laws and regulations. Any violations could result in enforcement actions, fines, civil and criminal penalties, damages, injunctions, or reputational harm. If we are unable to comply with these laws and regulations or manage the complexity of our global operations successfully, our business, results of operations, and financial condition could be adversely affected.

We store personal information and other customer data, which subjects us to various data privacy laws, governmental regulations, and other related legal obligations, and any actual or perceived failure to comply with such requirements could harm our business.

We store personal information and other customer data, as well as use certain cookies on our website, that are subject to numerous federal, state, local, and foreign laws regarding privacy and the storing and protection of personal information and other customer data, and disclosure requirements regarding the use and certain breaches of such laws. For example, we are subject to the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act of 2020 (CPRA), among other laws and regulations around the world. Other comprehensive data privacy or data protection laws or regulations requiring local data residency and/or restricting the international transfer of data have been passed or are under consideration in other jurisdictions. In addition, some industries have industry-specific requirements relating to compliance with certain security and regulatory standards, such as those required by the Health Insurance Portability and Accountability Act (HIPAA). For example, HIPAA imposes privacy, security, and breach reporting obligations with respect to individually identifiable health information upon “covered entities” (e.g., health plans, health care clearinghouses, and certain health care providers), and their respective business associates, individuals, or entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. Such laws give rise to an increasingly complex set of compliance obligations on us regarding our ability to gather, use, and store customer data and customer account data.

These privacy and data protection laws are subject to rapid change, limited timeframes to implement changes, differing interpretations, and can be inconsistent among regulatory frameworks or conflict with other rules or our business practices. We strive to comply with all applicable laws, policies, legal obligations, and industry codes of conduct relating to privacy and data protection to the extent possible. Our efforts to comply with the complex matrix of data privacy laws around the world subjects us to increasing costs to review and comply with such laws, including updating our policies, procedures, and business practices to address such evolving privacy laws. We also make public statements and commitments regarding our

49

use and disclosure of personal information through our privacy policy, information provided on our website, and data processing agreements with customers and other third parties. Because the interpretation and application of data protection laws, regulations, standards, and other obligations are often uncertain and in flux, and sometimes contradictory, it is possible that the scope and requirements of these laws and other obligations may be interpreted and applied in a manner that is inconsistent with our practices, and our efforts to comply with rapidly evolving data protection laws and obligations may be unsuccessful. For example, we previously relied on the EU-US Privacy Shield framework, which was invalidated by a European court in July 2020. As a result of such a decision, we have had to take additional steps to comply with applicable EU data protection requirements, including implementation of standard contractual clauses.

Any failure, or perceived failure, by us to comply with applicable privacy and security laws, policies, or related contractual obligations, or any compromise of security that results in unauthorized access, or the use or transmission of personal information or other customer data, could result in a variety of claims against us, including governmental enforcement actions and investigations, audits, inquiries, whistleblower complaints, class action privacy litigation in certain jurisdictions, and proceedings by data protection authorities. For example, under the GDPR we may be subject to fines of up to €20 million or up to 4% of the total worldwide annual group turnover of the preceding financial year, as well as potentially face claims from individuals. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action may increase the likelihood of, and risks associated with, data breach litigation. The CPRA added new requirements and consumer privacy rights as well as the creation of the California Privacy Protection Agency as a dedicated agency to implement and enforce California state privacy laws, investigate violations and assess penalties. Any new or currently applicable privacy and security laws, policies, or related contractual obligations may be enacted, adopted, or modified, the result of which may impact our compliance efforts, especially when certain emerging privacy laws are still subject to a high degree of uncertainty as to their interpretation, application and impact. Any non-compliance with data privacy requirements could subject us to significant fines and penalties, adverse media coverage, reputational damage, the loss of current and potential customers, loss of export privileges, or criminal or other civil sanctions, any of which could materially adversely affect our business and financial condition.

Our business is substantially dependent on mid-market organizations, which may be more vulnerable to market fluctuations and other economic factors, and their vulnerability to such factors could negatively impact our business.

If we are unable to successfully market and sell our cloud services to mid-market organizations, our ability to grow our revenue and achieve profitability will be harmed. We expect it will be more difficult and expensive to attract and retain mid-market organization customers than other customers because mid-market organizations are more frequently forced to curtail or cease operations due to the sale or failure of their business; can be more difficult to identify and may require more expensive, targeted sales campaigns; and generally have lesser amounts of data to store than larger organizations, thus requiring us to successfully sell to and support more mid-market organizations for meaningful revenue impact. In addition, mid-market organizations frequently have limited budgets and are more likely to be significantly affected by economic downturns than larger, more established companies. For example, recent high inflation and recession concerns in the United States could have a greater adverse impact on mid-market organizations. As a result, mid-market organizations may choose to spend funds on items other than our cloud services, particularly during difficult economic times. If we do not achieve continued success among mid-market organizations, our business, operating results, and future growth would be adversely affected.

We are dependent on a small number of service offerings, and any reduced market adoption of these offerings would result in lower revenue and harm our business.

As a specialized cloud vendor, we are dependent on a small number of offerings focused on cloud storage and computer backup, and a limited number of corresponding use cases. Our B2 Cloud Storage and Computer Backup offerings have accounted for substantially all of our total revenue to date and we anticipate that they will continue to do so for the foreseeable future. As a result, our revenue could be reduced as a result of any general or industry decline in demand for cloud-based storage solutions, particularly given that we would not have meaningful revenue from other market sectors to offset any temporary or longer-term downturn in demand for cloud-based storage solutions.

Adverse economic conditions may adversely impact our revenue and profitability.

Our operations and financial performance depend in part on worldwide economic conditions and the impact these conditions have on levels of spending on cloud storage solutions. Our business depends on the overall demand for these products and on the economic health and general willingness of our current and prospective customers to purchase our

50

cloud services. Some of our paying customers may view use of cloud storage services as a discretionary purchase and may reduce their discretionary spending on our cloud services during an economic downturn. Weak economic conditions, whether due to the banking and financial crises, COVID-19, inflation, uncertainty relating to the hostilities with Russia-Ukraine and Israel-Hamas, and the potential escalation of geopolitical tensions that could also directly or indirectly involve other countries, including the United States, could cause a reduction in spending on products and solutions storage. Inflation has increased significantly over levels from the last few years in the United States amid a slowing economy and there are numerous indicators suggesting a potential economic recession in the United States and other regions of the world. Any such conditions could reduce sales, lengthen sales cycles, increase customer churn, and lower demand for our cloud services, which could adversely affect our business, results of operations, and financial condition. We also have been, and may in the future be, subject to increased energy costs, particularly with respect to our data center operations in Europe and elsewhere, which could adversely affect our expenses and business.

Our ability to maintain customer adoption and satisfaction depends in part on the ease of use of our cloud services, and any such failure could have an adverse effect on our business.

Our success in retaining existing customers and obtaining new customers is dependent in part on the ease of use of our cloud services. If our platform and cloud services, including new service offerings and features as they become available, become more complicated and less easy-to-use, customers could experience increased difficulties or disruption with storing or accessing their data, and we may lose existing customers or experience increased challenges obtaining new customers or existing customers may not choose to use additional features of our cloud services. In addition, our customers sometimes depend on our technical support services to resolve issues relating to our platform. If we do not succeed in helping our customers quickly resolve issues or provide effective ongoing education related to our platform, our reputation and business may be harmed.

Future acquisitions and investments could disrupt our business and harm our financial condition and operating results.

Our success will depend, in part, on our ability to grow our business in response to changing technologies, customer demands, and competitive pressures. In some circumstances, we may choose to do so through the acquisition of complementary businesses and technologies rather than through internal development. The identification of suitable acquisition candidates can be difficult, time-consuming, and costly, and we may be unable to successfully complete proposed acquisitions. The risks we face in connection with acquisitions include:

•diversion of management time and focus from operating our business to addressing acquisition integration challenges;

•coordination of research and development, operational, and sales and marketing functions;

•retention of key employees from the acquired company;

•cultural challenges associated with integrating employees from the acquired company into our organization;

•integration of the acquired company’s accounting, management information, human resources, and other administrative systems;

•the need to implement or improve controls, procedures, and policies at a business that prior to the acquisition may have lacked effective controls, procedures, and policies;

•liability for activities of the acquired company prior to our acquisition of them, including intellectual property infringement claims, violations of laws, commercial disputes, tax liabilities, and other known and unknown liabilities;

•unanticipated write-offs or charges; and

•litigation or other claims in connection with the acquired company, including claims from terminated employees, customers, former stockholders, or other third parties.

51

Future acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities, amortization expenses, incremental operating expenses, or the write-off of goodwill, any of which could harm our financial condition or operating results.

We may require additional capital to support our operations or the growth of our business, and we cannot be certain that this capital will be available on reasonable terms when required, or at all.

We may need additional financing to operate or grow our business. Our ability to obtain additional financing, if and when required, will depend on investor and lender demand, our operating performance, the condition of the capital markets, and other factors. For example, we often use leases to finance the equipment we use to provide our cloud-based services, and we have a revolving credit agreement with City National Bank. In addition, the stock market has recently experienced significant volatility, including with respect to technology stocks, due to high inflation, various economic headwinds and other factors. In the event of a failure of any financial institutions where we maintain deposits, we may lose timely access to our funds at such institutions and incur significant losses to the extent our funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. In addition, we use City National Bank, a subsidiary of RBC, for our banking needs. While we and our bank have not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption, greater uncertainty, and tightened lending standards. This may result in reduced access to capital, increased costs of capital, and reduced opportunities to invest with investment grade securities, which could also lower investment yields and investment income. Any such impact could have a material adverse effect upon our liquidity and business. Without additional access to this kind of capital on commercially reasonable terms, or at all, we may not be able to respond to increased demand for our cloud services on a timely or cost-effective basis. We cannot guarantee that additional financing will be available to us on favorable terms when required, or at all. If we raise additional funds through the issuance of equity, equity-linked, or debt securities, those securities may have rights, preferences, or privileges senior to the rights of our Class A common stock, and our existing stockholders may experience dilution. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support the operation or growth of our business could be significantly impaired and our operating results may be harmed.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to emerging growth companies could make our Class A common stock less attractive to investors.

We are an emerging growth company, and for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to “emerging growth companies,” including: not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002, as amended (the Sarbanes Oxley Act), reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to avail ourselves of this accommodation allowing for delayed adoption of new or revised accounting standards, and therefore, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. We could be an emerging growth company for up to five years following the completion of our IPO or until we reach certain thresholds. Investors may find our Class A common stock less attractive due to our election to rely on these exemptions and there may be a less active trading market for our Class A common stock and the market price of our Class A common stock may be more volatile.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our results of operations.

All of our sales contracts, and substantially all of our operations and related financial arrangements, are currently denominated in U.S. dollars and therefore, our revenue and business operations are not directly subject to significant foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our cloud services to our customers outside of the United States, which could reduce demand for our cloud services and adversely affect our financial condition and results of operations. In addition, as we expand our international operations, we may become more exposed to foreign currency risk and may have some of our sales and other operations denominated in one or more currencies other than the U.S. dollar. If we become more exposed to currency fluctuations and are unable to successfully hedge against the risks associated with currency fluctuations, our results of operations could be materially and adversely affected.

52

Any future litigation against us could be costly and time-consuming to defend.

We may become subject to legal proceedings, investigations, and claims that arise in the ordinary course of business. For example, we may be subject to claims brought by customers, vendors or other third parties in connection with various types of disputes, including relating to commercial or contract matters, violation of securities laws, intellectual property laws or other laws, or privacy or other data breaches, or employment claims made by our current or former employees. Litigation can often be expensive, even when there is a successful outcome, and can divert management’s attention and resources, which could harm our business and financial condition. Any adverse outcome could also result in significant monetary damages or other types of unfavorable relief, which could harm our business as well as our reputation. Although we may have various insurance policies, insurance might not cover such claims or provide sufficient payments to cover all the costs to resolve one or more such claims, and might not continue to be available on terms acceptable to us, including premium increases or the imposition of large deductible or co-insurance requirements. In addition, we may also be subject to subpoena requests from third parties as well as governmental agencies from time to time that require us to provide certain information relating to matters targeted against other third parties, which can be time consuming.

The COVID-19 pandemic has impacted how we, our customers, and our partners are operating, and any re-emergence of the pandemic could result in a material adverse effect on our business.

In prior periods, the COVID-19 pandemic, and measures taken to control its spread such as travel restrictions, shelter-in-place orders, and business shutdowns, have affected all of the regions in which we conduct business and in which our customers, partners, and suppliers are located; have adversely impacted global economic activity; and have contributed to volatility in financial markets. The pandemic has resulted in various changes to customer business dynamics and may have impacted the storage needs of our customers and prospective customers as well as additional costs and other adverse business conditions affecting our company and our customers and partners, which may occur again if pandemic conditions return. In addition, work from home and related business practice modifications present significant challenges to maintaining our corporate culture, including employee engagement and productivity, as we make additional adjustments following the pandemic.

Risks Related to Reliance on Infrastructure and Third Parties

We rely on third-party vendors and suppliers, including data center and hard drive providers, which may have limited sources of supply, and this reliance exposes us to potential supply and service disruptions that could harm our business.

We depend on a limited number of third-party data centers and other providers to safely house our equipment and provide sufficient power, bandwidth, and other infrastructure needs to support our operations and cloud services. We also rely on key components for our platform, including hard drives and semiconductors, which come from limited sources of supply. For example, the 2011 Thailand floods decreased hard drive supply globally due to related manufacturing stoppages. A similar decrease in hard drive availability could negatively impact our operations. Various events, including a pandemic or fluctuating demands in the cryptocurrency mining markets have impacted, and could impact in the future, our ability to source components in a timely and cost-effective manner from third-party suppliers. For example, for a limited period of time starting in April 2020, we acquired additional hard drives and related infrastructure through finance lease agreements in order to minimize the impact of potential supply chain disruptions due to the COVID-19 pandemic. The additional leased hard drives resulted in a higher balance of capital equipment and related lease liability, an increase in cash used in financing activities from principal payments, as well as a higher ongoing interest and depreciation expense related to these lease agreements. The semiconductor industry also experienced a global chip shortage due to the COVID-19 pandemic and various other factors. Current or future supply chain interruptions that could be exacerbated by global political tensions, such as the Russia-Ukraine and Israel-Hamas hostilities, or tensions between Taiwan and China, particularly if those tensions escalate into an armed conflict or directly or indirectly involve other countries, including the United States, that could disrupt the global supply chain and result in the implementation of trade barriers, including boycotts or the use of economic sanctions and export control restrictions, any of which could negatively impact our ability to acquire hard drives and semiconductors. In addition, our business could be harmed in the event of any industry consolidations, acquisitions or other restructuring events. For example, in September 2023, Toshiba Corp., one of our hard drive suppliers, announced the completion of a buy-out by various private equity firms and others. Also, in October 2023, Western Digital, another one of our hard drive suppliers, announced that it would spin-out its hard drive and other selected businesses into a separate company. It is unclear what, if any, changes may occur as a result of the Toshiba buyout and Western Digital spin-out. Any shortage of key components, including hard drives, could materially and adversely affect our ability to provide our cloud services, as well as negatively impact our financial results by increasing our costs, lease liabilities, interest and depreciation expenses, and inventory levels. Shortages or pricing fluctuations could be material in the future. In the event of a shortage,

53

supply interruption, material pricing change or other significant events involving one of our suppliers, we may be unable to develop alternate sources in a timely manner or at all. For example, a third party vendor that operated one of our multiple data center locations, filed for bankruptcy under Chapter 11 under the United States Bankruptcy Code in 2022. This bankruptcy matter was resolved without disruption to normal operations, but future bankruptcies or similar actions affecting our third-party hosted data center providers could result in disruptions to the company, and access to customer data may become unavailable or customer data could be lost, and it may take a significant period of time to achieve full resumption of our cloud services. Developing alternate sources of supply for these infrastructure needs, and transitioning our customers’ data from one provider to another, may result in loss of availability of our services for a period of time, be time-consuming, costly, difficult, and increase the risk of damage and loss. We may also be unable to source them on terms that are acceptable to us, or at all, which may undermine our ability to operate or scale our platform and harm our business.

Our business depends, in part, on the success of our strategic relationships with third parties.

To maintain and grow our business, we anticipate that we will continue to depend on relationships with third parties, such as channel partners and integrators, which are becoming an increasingly important part of our business and our sales and marketing strategy. Identifying partners and negotiating and building relationships with them requires significant time and resources. Our competitors may be effective in providing incentives to third parties to favor their services over us. In addition, any industry consolidation of such partners or integrators by our competitors or others could result in a decrease in the number of our current and potential customers, as these partners or integrators may no longer facilitate the adoption of our applications by potential customers. Interoperability between our platform and other third-party platforms is also important to our business. Further, some of our partners or integrators are or may become competitive with certain aspects of our cloud services and may elect to no longer integrate with, or support, our platform and cloud services. If we are unsuccessful in establishing or maintaining our relationships with such third parties and maintaining interoperability, our ability to compete in the marketplace or to grow our revenue could be impaired, and our business may suffer. Even if we are successful, we cannot assure you that these relationships will result in increased customer usage of our cloud services or increased revenue.

Our business is exposed to risks associated with online payment processing methods.

Many of our customers pay for our cloud services and products using credit cards. We rely on internal systems as well as those of third parties, including Stripe, to process payments. Acceptance and processing of these payment methods are subject to certain rules and regulations and require payment of interchange and other fees. To the extent there are increases in payment processing fees, material changes in the payment ecosystem, such as large re-issuances of payment cards, delays in receiving payments from payment processors, changes to rules or regulations concerning payment processing, loss of payment partners, and/or disruptions or failures in our payment processing systems or payment products, including products we use to update payment information, our revenue, operating expenses, and results of operation could be adversely impacted. For example, in response to the Russian attack on Ukraine that began in February 2022, the United States and many other countries began imposing sanctions on Russia and certain other regions, including goods and services imported and exported to Russia and certain other regions. In addition, various banking institutions and companies, including Stripe and credit card companies, began prohibiting any payments from persons located in Russia, which impacts our ability to receive payments from, and transact certain types of business operations with, our customers, and potential new customers, that are located in those regions. Although we do not have a significant number of customers located in those regions, such actions will have some impact on our business. It is also difficult to predict how long the conflict may last, how the conflict could escalate, and how the sanctions may evolve, which could cause a greater adverse impact on our business and operations than we expect.

We rely on third-party software for certain essential financial and operational services, and a failure or disruption in these services could materially and adversely affect our ability to manage our business effectively.

We rely on third-party software to provide many essential financial and operational services to support our business, including HubSpot, NetSuite, PagerDuty, and Zendesk. Some of these vendors are less established and have shorter operating histories than traditional software vendors. Moreover, many of these vendors provide their services to us via a cloud-based model instead of software that is installed on our premises. As a result, we depend upon these vendors to provide us with services that are always available and are free of errors or defects that could cause disruptions in our business processes. Any failure by these vendors to do so, or any disruption in our ability to access the internet, would materially and adversely affect our ability to manage our operations, disrupt the delivery of our cloud services to customers, and affect other areas such as our ability to timely provide required financial reporting.

54

We are a smaller reporting company, and any decision on our part to comply only with reduced reporting and disclosure requirements applicable to such companies could make our ordinary shares less attractive to investors.

As of June 30, 2023, we qualified as a “smaller reporting company,” as defined in the Exchange Act. For as long as we continue to be a smaller reporting company, we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies that are not smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and only being required to provide two years of audited financial statements in annual reports.

We will remain a smaller reporting company so long as, as of June 30 of the preceding year, (i) the market value of our ordinary shares held by non-affiliates, or our public float, is less than $250.0 million; or (ii) we have annual revenues less than $100.0 million and either we have no public float or our public float is less than $700.0 million.

If we take advantage of some or all of the reduced disclosure requirements available to smaller reporting companies, investors may find our Class A common stock less attractive, which may result in a less active trading market for our Class A common stock and greater stock price volatility. For example, for so long as we are a smaller reporting company and not classified as an “accelerated filer” or “large accelerated filer” pursuant to SEC rules, we will be exempt from the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act.

Risks Related to Accounting and Tax Matters

We have identified material weaknesses in our internal controls over financial reporting, and the failure to achieve and maintain effective internal controls over financial reporting could harm our business and negatively impact the value of our Class A common stock.

We have identified material weaknesses in our internal controls over financial reporting, and if we are not able to effectively remediate our outstanding material weaknesses or are otherwise unable to maintain an effective system of internal controls over financial reporting, we may not be able to accurately report our financial results or timely file our periodic reports. As a result, investors may lose confidence in the accuracy and completeness of our financial reports, and the market price of our Class A common stock may be materially impacted.

Our management determined that as of December 31, 2022 we did not maintain effective internal controls over financial reporting, and as of September 30, 2023, we had three outstanding material weaknesses, specifically related to control activities, as follows:

i.Our controls were not operating effectively to allow sufficient and timely review of significant accounting transactions, reconciliations, and presentation of the statement of cash flows. These deficiencies resulted in errors in cash and cash equivalents, prepaid expenses and other current assets, property and equipment, capitalized internal-use software, lease liability and sale leaseback transactions, accrued compensation and income tax;

ii.our controls over certain equity transactions were not operating effectively to allow management to timely identify errors related to the recording of those transactions; specifically, we did not have sufficient technical resources to appropriately identify errors in the accounting for equity awards and preferred stock transactions, resulting in misstatements relating to completeness and accuracy of stock-based compensation and classification of equity instrument; and

iii.our controls were not adequately designed and operating effectively to allow sufficient and timely review of our going concern assessment. Within the going concern assessment, this resulted in incorrect assumptions used in the forecasted cash flows and computational errors.

We have dedicated significant effort and resources towards measures to remediate the identified material weaknesses (See Part 1, Item 4. Controls and Procedures included elsewhere in this Quarterly Report on Form 10-Q for additional information regarding remediation efforts). We are in the process of designing and implementing internal controls intended to address our outstanding material weaknesses, and are also testing the operating effectiveness of these controls. The outstanding material weaknesses cannot be considered fully remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

We cannot assure you that the measures we have taken to date will be sufficient to remediate the outstanding material weaknesses we identified or prevent additional material weaknesses in the future. Although we plan to complete this remediation, if the steps we take do not remediate these material weaknesses in a timely or sufficient manner, there could

55

continue to be a reasonable possibility that these control deficiencies could result in a material misstatement of our annual or interim financial statements that would not be prevented or detected on a timely basis.

Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal controls over financial reporting until after we are no longer an “emerging growth company” as defined in the JOBS Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal controls over financial reporting is documented, designed, or operating. Any failure to maintain effective disclosure controls and internal controls over financial reporting could materially and adversely affect our business, results of operations, and financial condition and could cause a decline in the trading price of our Class A common stock.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, we may be unable to produce timely and accurate financial statements or comply with applicable regulations, which could negatively impact the price of our Class A common stock.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act), the Sarbanes-Oxley Act, and the rules and regulations of the Nasdaq Global Market. We expect that the requirements of these rules and regulations will continue to increase our legal, accounting, and financial compliance costs, make some activities more difficult, time-consuming, and costly, and place significant strain on our personnel, systems, and resources.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures and internal controls over financial reporting and expect that we will need to continue to expend significant resources, including accounting-related costs, and significant management oversight, to meet such requirements. However, our current controls and any new controls that we develop may not be adequate, and weaknesses in our disclosure controls may be discovered in the future. Additionally, we have identified material weaknesses in our internal controls over financial reporting, and such weaknesses may be discovered in the future. See “—We have identified material weaknesses in our internal controls over financial reporting, and the failure to achieve and maintain effective internal controls over financial reporting could harm our business and negatively impact the value of our Class A common stock.” Any failure to develop or maintain effective controls or any difficulties encountered in their implementation or improvement could harm our results of operations or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal controls over financial reporting also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal controls over financial reporting that we will eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls and procedures and internal controls over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our Class A common stock.

Because we recognize revenue from our subscription services over the term of the subscription, downturns or upturns in new business may not be immediately reflected in our operating results.

We generally recognize revenue from customers of our subscription agreements related to data backup services ratably over the terms of their subscription agreements, a majority of which are one or two-year agreements. Accordingly, the corresponding revenue we report in each quarter from such arrangements is the result of subscription agreements entered into during previous quarters. Consequently, a decline in new or renewed subscriptions in any one quarter may only be partially reflected in our revenue results for that quarter. However, any such decline will negatively affect our revenue in future quarters. Accordingly, the effect of significant downturns in sales and market acceptance of our cloud services, and potential changes in our retention rate may not be fully reflected in our operating results until future periods. This subscription model also makes it difficult for us to rapidly increase our revenue through additional subscription sales in any period as part of new growth initiatives or otherwise, as revenue from new customers must be recognized over the applicable subscription term.

Our operating results may be harmed if we are required to collect sales or other related taxes for our cloud services in jurisdictions where we have not historically done so.

We collect sales and value-added tax in connection with our cloud services in a number of jurisdictions. One or more states or countries may seek to impose incremental or new sales, use, or other tax collection obligations on us, including for past

56

sales by us or our resellers and other partners. Online sellers can be required to collect sales and use tax despite not having a physical presence in the buyer’s state. A successful assertion by a state, country, or other jurisdiction that we should have been or should be collecting additional sales, use, or other taxes on our cloud services could, among other things, result in substantial tax liabilities for past sales, create significant administrative burdens for us, discourage users from purchasing our platform, or otherwise harm our business, results of operations, and financial condition.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2022 we had net operating loss carryforwards for U.S. federal income tax purposes of $63.4 million available to offset future U.S. federal taxable income. Also, as of December 31, 2022, we had net operating loss carryforwards for state income tax purposes of $33.5 million available to offset future state taxable income. If not utilized, both the federal and state tax credit carryforwards will begin to expire in 2027.

Utilization of our net operating loss carryforwards and other tax attributes, such as research and development tax credits, may be subject to annual limitations, or could be subject to other limitations on utilization or benefit due to the ownership change limitations provided by Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), and other similar provisions. Under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” our ability to use pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset post-change income may be limited. Similar rules may apply under state tax laws. At this time, we have not finalized a study to assess whether such an ownership change has occurred, or whether there have been multiple ownership changes since our formation. We may experience ownership changes in the future as a result of subsequent changes in our stock ownership, some of which may be outside our control. Accordingly, our ability to utilize the aforementioned carryforwards may be limited.

Changes in tax laws could materially affect our financial condition, results of operations and cash flows.

We are unable to predict what changes to the tax laws of the U.S. and other jurisdictions may be proposed or enacted in the future or what effect such changes would have on our business. Any significant increase in our future effective tax rate could have a material adverse impact on our business, financial condition, results of operations, or cash flows.

The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect us or holders of our common stock. For example, under Section 174 of the Code, in taxable years beginning after December 31, 2021, expenses that are incurred for research and development in the U.S. will be capitalized and amortized, which may have an adverse effect on our cash flow. In recent years, many such changes have been made, and changes are likely to continue to occur in the future. It cannot be predicted whether, when, in what form or with what effective dates tax laws, regulations and rulings may be enacted, promulgated or issued, which could result in an increase in our or our shareholders’ tax liability or require changes in the manner in which we operate in order to minimize or mitigate any adverse effects of changes in tax law.

If our estimates or judgments relating to our critical accounting policies prove to be incorrect, our results of operations could be adversely affected.

The preparation of financial statements in conformity with United States Generally Accepted Accounting Principles requires management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes appearing elsewhere in this Quarterly Report on Form 10-Q or in our most recent Annual Report on Form 10-K. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates.” The results of these estimates form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Significant estimates and assumptions involve those related to costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, valuation of our Employee Stock Purchase Plan (“ESPP”) expense, and accounting for taxes, including estimates for deferred tax assets, valuation allowance and uncertain tax positions. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions.

57

Risks Related to Intellectual Property

Assertions by a third party that our cloud services infringe, misappropriate, or otherwise violate their intellectual property could subject us to costly and time-consuming litigation and adversely impact our business.

There is frequent litigation in the software and technology industries based on allegations of infringement, misappropriation, or other violations of intellectual property rights. Some software and technology companies, including some of our competitors, as well as non-practicing entities, own patents, trademarks, copyrights and other intellectual property rights that they may use to assert claims against us. In our case, third parties have asserted, and may in the future assert, that we have infringed, misappropriated, or otherwise violated their patents or other intellectual property rights. For example, we have faced patent infringement claims from other non-practicing entities in the past. There may be intellectual property rights held by others, including issued or pending patents, that cover significant aspects of our technologies or solutions, and we cannot assure you that we are not infringing, misappropriating, or violating, and have not infringed, misappropriated, or violated, any third-party intellectual property rights or that we will not be held to have done so or be accused of doing so in the future. In addition, as we face increasing competition and become increasingly visible as a publicly-traded company, or if we become more successful, the possibility of new third-party claims may increase.

Any claim that we have violated intellectual property or other proprietary rights of third parties, with or without merit, could be time-consuming and costly to address and resolve, could divert the time and attention of management and technical personnel from our business, could place limitations on our ability to use our current websites and technologies, and could result in an inability to market or provide all or a portion of our cloud services. Furthermore, we could be required to pay substantial monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a party’s intellectual property rights. We may also be required to enter into a royalty or licensing agreement that could include significant upfront and future licensing fees or expend significant resources to redesign our technologies or solutions, which efforts may not be timely or prove successful at all and require us to indemnify customers or other third parties. Royalty or licensing agreements may be unavailable on terms acceptable to us, or at all. If we cannot develop or license technology for any allegedly infringing aspect of our business, we could be forced to limit our cloud services and may be unable to compete effectively. Any of these events could have a material adverse effect on our business.

If we are unable to adequately establish, maintain, protect, and enforce our intellectual property and proprietary rights, our reputation may be harmed, we may be subject to litigation, and our business may be adversely affected.

Our future success and competitive position depend in large part on our ability to establish, maintain, protect, and enforce our intellectual property and proprietary rights. We do not own any issued patents and rely on a combination of trademark, copyright, and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish and protect our proprietary rights, all of which provide only limited protection and may not now or in the future provide us with a competitive advantage. The steps we have taken and will take may not prevent unauthorized use, reverse engineering, or misappropriation of our technologies and we may be unable to detect any of the foregoing. Furthermore, effective trademark, copyright, and trade secret protection may not be available in every country in which our cloud services are available. Our lack of patent protection may restrict our ability to protect our technologies and processes from competition. Defending and enforcing our intellectual property rights may result in litigation, which can be costly and divert management attention and resources. If our efforts to protect our technologies and intellectual property are inadequate, the value of our brand and other intangible assets may be diminished and competitors may be able to mimic our cloud services. Any of these events could have a material adverse effect on our business.

With respect to our technology platform, we consider trade secrets and know-how to be one of our primary sources of intellectual property. However, trade secrets and know-how can be difficult to protect. The use of generative artificial intelligence tools could also expose us to inadvertently disclosing trade secrets or other confidential information or inadvertently cause us to violate third party intellectual property rights. We seek to protect these trade secrets and other proprietary technology, in part, by internal controls and policies as well as entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, outside contractors, consultants, advisors, and other third parties. We also enter into confidentiality and invention assignment agreements with our employees and consultants. The confidentiality agreements are designed to protect our proprietary information and, in the case of agreements or clauses containing invention assignment, to grant us ownership of technologies that are developed through a relationship with employees or third parties. We cannot guarantee that we have entered into such agreements with each party that may have or has had access to our trade secrets or proprietary information, including our technology and processes. Despite these efforts, no assurance can be given that the confidentiality agreements we enter into or our other

58

internal controls and policies will be effective in controlling access to such proprietary information and trade secrets. The confidentiality agreements on which we rely to protect certain technologies may be breached, and these and other actions that we take may not be adequate to protect our confidential information, trade secrets, and proprietary technologies and may not provide an adequate remedy in the event of unauthorized use or disclosure of our confidential information, trade secrets or proprietary technology. Further, these actions do not prevent our competitors or others from independently developing the same or similar technologies and processes, which may allow them to provide a service similar or superior to ours, which could harm our competitive position.

Our use of “open-source” software could negatively affect our ability to sell our cloud services and subject us to possible litigation.

A portion of the technologies used by us incorporates “open-source” software, and we may incorporate open-source software in the future. Such open-source software is generally licensed by its authors or other third parties under open-source licenses. Companies that incorporate open-source software into their solutions have, from time to time, faced claims challenging the use of open-source software and compliance with open-source license terms. These licenses may subject us to certain unfavorable conditions, including requirements that we offer all or parts of our technology or services that incorporate the open-source software at no cost, that we make publicly available source code for modifications or derivative works we create based upon, incorporating, or using the open-source software, and/or that we license such modifications or derivative works under the terms of the particular open-source licensor other license granting third parties certain rights of further use. Although we monitor our use of open-source software, we cannot assure you that all open-source software is reviewed prior to use in our cloud services, that our developers have not incorporated open-source software into our technology platform or services, or that they will not do so in the future. In the event that we become subject to such claims, we could be subject to significant damages, enjoined from the sale of our solutions that contained the open-source software, and required to comply with onerous conditions. In addition, the terms of open-source software licenses may require us to provide software that we develop using such open-source software to others on unfavorable license terms. As a result of our current or future use of open-source software, we may face claims or litigation, be required to release our proprietary source code, pay damages for breach of contract, re-engineer our solutions, discontinue making our solutions available in the event re-engineering cannot be accomplished on a timely basis or take other remedial action. Any such re-engineering or other remediation efforts could require significant additional research and development resources, and we may not be able to successfully complete any such re-engineering or other remediation efforts on a timely basis, or at all. Any of these risks could be difficult to eliminate or manage, and, if not addressed, could disrupt the distribution and sale of our solutions and have a material adverse effect on our business and operating results.

Risks Related to Ownership of Our Class A Common Stock

Anti-takeover provisions contained in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, as well as provisions of Delaware law, could impair a takeover attempt.

Our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, and Delaware law contain provisions which could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by our Board of Directors. Among other things, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws include provisions:

•creating a classified Board of Directors whose members serve staggered three-year terms;

•authorizing “blank check” preferred stock, which could be issued by our Board of Directors without stockholder approval and may contain voting, liquidation, dividend, and other rights superior to our common stock;

•limiting the liability of, and providing indemnification to, our directors and officers;

•limiting the ability of our stockholders to call and bring business before special meetings;

•requiring advance notice of stockholder proposals for business to be conducted at meetings of our stockholders and for nominations of candidates for election to our Board of Directors; and

•controlling the procedures for the conduct and scheduling of Board of Directors and stockholder meetings.

59

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management.

As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation law, which prevents certain stockholders holding more than 15% of our outstanding capital stock from engaging in certain business combinations without approval of the holders of at least two-thirds of our outstanding common stock not held by such stockholder. Any provision of our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws, or Delaware law that has the effect of delaying, preventing, or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock, and could also affect the price that some investors are willing to pay for our Class A common stock.

The market price of our Class A common stock has been, and will likely continue to be, volatile, and you could lose all or part of your investment.

Prior to the listing of our Class A common stock, there was no public market for shares of our Class A common stock. Since our IPO, the stock price of our Class A common stock has experienced very high volatility and the market prices of securities of other newly public companies have historically been highly volatile. The market price of our Class A common stock could be subject to wide fluctuations in response to various factors, including those listed in this Quarterly Report on Form 10-Q, some of which are beyond our control and may not be related to our operating performance.

Fluctuations in the price of our Class A common stock could cause you to lose all or part of your investment because you may be unable to sell your shares at or above the price you paid. Factors that could cause fluctuations in the market price of our Class A common stock include the following:

•price and volume fluctuations in the overall stock market from time to time;

•volatility in the market prices and trading volumes of technology stocks;

•changes in operating performance and stock market valuations of other technology companies generally or those in our industry in particular;

•sales of shares of our Class A common stock by us or our stockholders;

•failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts who follow us, or our failure to meet these estimates or the expectations of investors;

•the financial projections we may provide to the public, any changes in those projections or our failure to meet those projections;

•announcements by us or our competitors of new products or services;

•the public’s reaction to our press releases, other public announcements, and filings with the SEC;

•rumors and market speculation involving us or other companies in our industry;

•actual or anticipated changes in our operating results or fluctuations in our operating results;

•actual or anticipated developments in our business, our competitors’ businesses, or the competitive landscape generally;

•litigation involving us, our industry, or both, or investigations by regulators into our operations or those of our competitors;

•developments or disputes concerning our intellectual property or other proprietary rights;

•announced or completed acquisitions of businesses or technologies by us or our competitors;

•new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

60

•changes in accounting standards, policies, guidelines, interpretations, or principles;

•outbreaks of war or other hostilities;

•any significant change in our management;

•the impact of the COVID-19 or similar pandemic; and

•general economic conditions and slow or negative growth of our markets.

We may fail to meet our publicly announced guidance or other expectations about our business, which could cause our stock price to decline.

We may provide from time to time guidance regarding our expected financial and business performance, which may include projections regarding sales and production, as well as anticipated future revenues, gross margins, profitability, and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process, and our guidance may not ultimately be accurate and has in the past been inaccurate in certain respects, such as the timing of new products. Our guidance is based on certain assumptions such as those relating to anticipated production and sales, average sales prices, supplier and commodity costs, and planned cost reductions. If our guidance is not accurate or varies from actual results due to our inability to meet our assumptions or the impact on our financial performance that could occur as a result of various risks and uncertainties, the market value of our Class A common stock could decline significantly.

Sales of a substantial number of our Class A common stock in the public market could cause our share price to fall.

The market price of our Class A common stock could decline as a result of sales of a large number of shares of our Class A common stock in the market, and the perception that these sales could occur may also depress the market price of our Class A common stock. In addition, our daily trading volume may be limited and significantly less than the amount of shares available for sale. In the event that the number of our Class A common stock shares offered for sale on any given day exceeds the existing demand for our shares, it may cause our stock price to fall.

We may also issue additional shares of our Class A common stock, convertible securities or other equity, including pursuant to our equity compensation plans. Such issuances could be dilutive to investors and could cause the price of shares of our Class A common stock to decline. New investors in such issuances could also receive rights senior to those of holders of shares of our Class A common stock.

The above factors may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. Any such sales also could cause the market price of our Class A common stock to fall and make it more difficult for you to sell shares of our Class A common stock.

If securities or industry analysts do not publish or cease publishing research or reports about us, our business, our market, or our competitors, or if they adversely change their recommendations regarding our Class A common stock, the market price of our Class A common stock and trading volume could decline.

The trading market for our Class A common stock will be influenced by the research and reports that securities or industry analysts may publish about us, our business, our market, or our competitors. If any of the analysts who may cover us adversely change their recommendations regarding our Class A common stock or provide more favorable recommendations about our competitors, the market price of our Class A common stock would likely decline. If any of the analysts who may cover us were to cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price of our Class A common stock or trading volume to decline.

We do not expect to declare any dividends in the foreseeable future.

We do not anticipate declaring any cash dividends to holders of our Class A common stock in the foreseeable future. Consequently, investors may need to rely on sales of our Class A common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not purchase shares of our Class A common stock.

61

Our Amended and Restated Certificate of Incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America are the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our Amended and Restated Certificate of Incorporation provides that the Court of Chancery of the State of Delaware and the federal district courts of the United States of America are the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees. Specifically, our Amended and Restated Certificate of Incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum provision for: (i) any derivative action or proceeding brought on behalf of us; (ii) any action asserting a claim of breach of a fiduciary duty; (iii) any action arising pursuant to any provision of the DGCL, our Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws (as either may be amended from time to time); (iv) any action to interpret, apply, enforce, or determine the validity of our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws; (v) any action asserting a claim against us that is governed by the internal affairs doctrine; or (vi) any action asserting an “internal corporate claim” as defined in the DGCL.

These exclusive forum provisions would not apply to suits brought to enforce a duty or liability created by the Exchange Act.

Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, our Amended and Restated Certificate of Incorporation further provides that the U.S. federal district courts are the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our Amended and Restated Certificate of Incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees. If a court were to find any of the exclusive forum provisions of our Amended and Restated Certificate of Incorporation to be inapplicable to or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

The requirements of being a public company, particularly after we are no longer an “emerging growth company”, may strain our resources, require us to incur substantial costs and will require substantial management attention.

As a public company, and particularly after we cease to be an “emerging growth company”, we have incurred and will continue to incur substantial legal, accounting, and other expenses that we did not incur as a private company. For example, we are subject to the reporting requirements of the Exchange Act, the applicable requirements of the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the rules and regulations of the SEC, and the listing standards of the NASDAQ Global Market. For example, the Exchange Act requires, among other things, we file annual, quarterly, and current reports with respect to our business, financial condition, and results of operations. Compliance with these rules and regulations has increased and will continue to increase our legal and financial compliance costs, and increase demand on our systems, particularly after we are no longer an emerging growth company. In addition, as a public company, we may be subject to stockholder activism, which can lead to additional substantial costs, distract management, and impact the manner in which we operate our business in ways we cannot currently anticipate. As a result of disclosure of information in filings required of a public company, our business and financial condition has become more visible, which may result in threatened or actual litigation, including by competitors.

Some members of our management team also have limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of

62

securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could adversely affect our business, financial condition, and results of operations.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 31, 2023. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as its annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of September 30, 2023, results of operations for the three and nine months ended September 30, 2023 and 2022, cash flows for the nine months ended September 30, 2023 and 2022, and stockholders' equity for the three and nine months ended September 30, 2023 and 2022. The results of operations for the three and nine months ended September 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.

Emerging Growth Company

The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an EGC.

Segment Information

The Company has a single operating and reportable segment. In reaching this conclusion, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources, and assess performance. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on an aggregated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Significant accounting policies

The Company’s significant accounting policies, certain of which have been updated below, are disclosed in the Company’s audited financial statements and related notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 31, 2023.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, valuation of the Company’s ESPP expense, and accounting for taxes, including estimates for deferred tax assets, valuation allowance and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates.

Foreign Currency

The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company and its subsidiaries is USD. Transaction gains and losses that arise from exchange rate fluctuations on monetary transactions denominated in a currency other than the functional currency are included in general and administrative on the condensed consolidated statements of operations when realized.

Concentrations and Risks and Uncertainties

Liquidity. The Company believes that its existing cash, cash equivalents and short-term investments together with cash provided by operations, will be sufficient to support its working capital and capital expenditure requirements for at least the next 12 months. However, to achieve its continued growth and objectives, the Company will need to obtain additional sources of financing which may include entering into lease agreements, sale-leaseback arrangements, credit facilities, and other debt financing arrangements for the purpose of acquiring infrastructure equipment and to fund its operations. In the event that the Company requires additional financing, it may not be able to raise such financing on terms acceptable to us or at all. If the Company is unable to obtain additional sources of financing, raise additional capital or generate cash flows necessary to expand its operations and invest in continued innovation, it may not be able to compete successfully, which would harm its business, results of operations and financial condition.

Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, short-term investments, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and short-term investments with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the balance sheets. In addition, the Company uses City National Bank, a subsidiary of Royal Bank of Canada (“RBC”), for its banking needs. While the Company and its bank has not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption and uncertainty, which could put additional pressures on the Company’s bank and other banks, and may negatively impact the availability and costs for various banking and investment offerings.

Vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply and service disruptions that could harm the Company’s business.

			September 30, 2023	December 31, 2022
Accounts payable concentration
Number of vendors			3	2
Total accounts payable balance represented by vendors listed above			28%	26%

Revenue. The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“Backblaze B2”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact to the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time.

Restructuring

Restructuring costs are comprised of severance costs related to workforce reductions. The Company recognizes restructuring charges when the liability is incurred. For involuntary terminations, employee termination benefits are accrued at the date (i) management has committed to a plan of termination, which includes identification of employees to be terminated and related information, (ii) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn, and (iii) employees have been notified of their termination dates and expected severance payments. For voluntary terminations, the Company recognizes a liability when the termination benefit has been irrevocably accepted by the employee.

Investments

The Company holds all investments on a held-to-maturity basis, and they are reported at amortized cost with realized gains or losses reported in earnings. The Company determines the appropriate classification of its investment in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date.

The Company will recognize an allowance for estimated credit losses on its held-to-maturity securities, using a forward-looking expected loss model, which reflects losses that are expected to be incurred over the life of the financial instrument. The Company uses a roll-rate method to determine the estimated credit losses using factors including historical global average default rates and expected recovery rates on similar credit quality, bond maturity and duration, along with historical experience, current conditions, and forecasts of future economic conditions, if available. The Company monitors the credit profile of its held-to-maturity securities on a periodic basis, using third party data to assess their credit ratings as well as any adverse conditions specifically related to the security.

The Company’s short-term investments include investment grade commercial paper with original maturities of 365 days or less at the date of purchase. Short-term investments are recorded at amortized cost on the balance sheet.

Accounting Pronouncements Recently Adopted

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires a financial asset measured at an amortized cost basis to be presented at the net amount expected to be collected, with further clarifications made more recently. For accounts receivables, unbilled receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2023 using the modified retrospective transition method with comparative periods continuing to be reported using the previous applicable guidance and determined that it did not have a material impact on its condensed consolidated financial statements.

Deferred Contract Costs

The Company’s amortization of deferred contract costs was $0.2 million for each of the three months ended September 30, 2023 and 2022, and was $0.7 million for each of the nine months ended September 30, 2023 and 2022. The amount of capitalized contract costs was $0.4 million as of both September 30, 2023 and December 31, 2022.

Deferred Revenue

Total deferred revenue was $27.2 million and $25.5 million as of September 30, 2023 and December 31, 2022, respectively. Revenue recognized for the three months ended September 30, 2023 and 2022 was $9.7 million and $9.2 million, respectively, and was $20.5 million and $19.3 million for the nine months ended September 30, 2023 and 2022, respectively, which was included in each deferred revenue balance at the beginning of each respective period. The Company’s deferred revenue as stated on its condensed consolidated balance sheets presented approximates its contract liability balance as of September 30, 2023 and December 31, 2022. The Company’s total deferred revenue balance as of September 30, 2023, approximates the aggregate amount of the transaction price allocated to remaining performance obligations (“RPOs”) as of that date. As of September 30, 2023, the Company's RPOs were $29.5 million. This amount includes deferred revenue arising from consideration invoiced for which the related performance obligations have not been satisfied, as well as future committed revenue for periods within current contracts with customers. As of September 30, 2023, the Company expects to recognize approximately 84% of its RPOs over the next 12 months, and substantially all of its RPOs over the next 24 months.

Fair Value Measurements

Fair Value MeasurementsThe Company classifies its held-to-maturity investments, which are comprised of investment grade commercial paper, within Level 2 of the fair value hierarchy because the fair value of these securities are priced by using inputs based on non-binding market consensus that are primarily corroborated by observable market data or quoted market prices for similar

instruments. The Company’s cash equivalents on its condensed consolidated balance sheet included commercial paper with an amortized cost and estimated fair value of $3.0 million as of September 30, 2023.

There were no transfers between levels of the fair value hierarchy for the three and nine months ended September 30, 2023 and the year ended December 31, 2022, respectively. The Company held no assets or liabilities that were measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, respectively.

As of December 31, 2022, the Company had $169 thousand in restricted cash related to the letter of credit established according to requirements under a lease agreement, reported as a component of other current assets on the condensed consolidated balance sheets. As of September 30, 2023, this balance is no longer restricted as the lease agreement and associated letter of credit have been completed.

Additionally, the Company had $6.1 million and $4.3 million in restricted cash as of September 30, 2023 and December 31, 2022, respectively, related to the line of credit agreement with City National Bank. See Note 11 for further details.

Commitments and Contingencies

Commitments and Contingencies

Finance Leases and Lease Financing Obligations

The Company enters into finance lease arrangements to obtain hard drives and related equipment for its data center operations. The term of these agreements primarily range from three to four years and certain of these arrangements have optional renewals to extend the term of the lease generally at a fixed price. Contingent rental payments are generally not included in the Company’s finance lease agreements. Finance leases are generally secured by the underlying leased equipment. The Company's finance leases have original lease periods expiring between 2023 and 2026. Finance leases are included in property and equipment, net on the Company’s condensed consolidated balance sheet.

As of September 30, 2023, the weighted average remaining lease term for finance lease and lease financing obligation agreements was 1.9 years and the weighted average discount rate for finance leases was 10.8%.

For the Company’s assets acquired through finance lease and lease financing obligation agreements, which are related to sale-leaseback agreements, depreciation expense was $3.9 million and $3.5 million for the three months ended September 30, 2023 and 2022, respectively, and was $11.2 million and $9.7 million for the nine months ended September 30, 2023 and 2022, respectively. Depreciation expense on assets acquired through the Company’s finance leases and lease financing obligations is included in cost of revenue in its condensed consolidated statements of operations.

During the three months ended September 30, 2023, total finance lease costs were $4.4 million, of which interest expense was approximately $0.7 million, and total lease financing obligation costs were $0.3 million, of which interest expense was approximately $0.1 million. During the three months ended September 30, 2022, total finance lease costs were $4.1 million, of which interest expense was approximately $0.9 million, and total lease financing obligation costs were $0.3 million, of which interest expense was approximately $0.1 million.

During the nine months ended September 30, 2023, total finance lease costs were $12.5 million, of which interest expense was approximately $2.2 million, and total lease financing obligation costs were $1.0 million, of which interest expense was approximately $0.2 million. During the nine months ended September 30, 2022, the total finance lease costs were $11.4 million, of which interest expense was approximately $2.5 million, and total lease financing obligation costs were $1.0 million, of which interest expense was approximately $0.3 million. The cash paid for interest on interest on finance lease and lease financing obligations was $2.4 million and $2.8 million for the nine months ended September 30, 2023 and 2022, respectively.

During the nine months ended September 30, 2023, the Company entered into one sale-leaseback arrangement with a vendor to provide $2.5 million in cash proceeds for previously purchased hard drives and related equipment. The Company concluded the related lease arrangements would be classified as a lease financing obligation as the Company is reasonably certain to exercise the purchase option within the arrangement. Therefore, the transaction was deemed a failed sale-leaseback and was accounted for as a financing arrangement. The assets continue to be depreciated over their useful lives, and payments are allocated between interest expense and repayment of the financing liability. The Company did not enter into any sale-leaseback arrangements during the nine months ended September 30, 2022.

The future minimum commitments for these finance leases and lease financing obligations as of September 30, 2023 were as follows (in thousands):

Year Ending December 31,	Finance leases		Lease financing obligations		Total

Operating Leases

The Company leases its facilities for data centers and office space under non-cancelable operating leases with various expiration dates. Certain lease agreements include renewal options to extend the lease term at a price to be determined upon exercise. These options are not reasonably certain to be exercised and therefore are not factored into the determination of lease payments. Contingent rental payments are generally not included in the Company’s lease agreements. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company's leases have original lease periods expiring between 2023 and 2031. The Company did not have a material amount of short-term leases as of September 30, 2023.

As of September 30, 2023, the weighted average remaining lease term for operating leases was approximately 5.7 years and the weighted average discount rate for operating leases was approximately 7.5%.

In July 2023, the Company entered into an operating lease agreement for purposes of consolidating and moving out of two offices into one, resulting in the recognition of $5.3 million of operating right-of-use assets and $5.2 million of operating lease liabilities, current and non-current, on its condensed consolidated balance sheet as of September 30, 2023.

The future minimum commitments for these operating leases as of September 30, 2023 were as follows (in thousands), which excludes amounts allocated to services under operating lease agreements that are considered non-lease components:

Year Ending December 31,
Remaining of 2023	$	640

2027	2,131
Thereafter	3,558
Total future minimum operating lease commitments	12,895
Less imputed interest	(2,379)
Total liability	$	10,516

Non-lease components included in the Company’s colocation lease agreements are related to non-tangible utilities and services used in its data center operations. The Company used judgment and third-party data in determining the stand-alone price for allocating consideration to lease and non-lease components under these colocation lease agreements, such as, the price of utilities as compared to its tangible data center footprint within each colocation facility.

The future minimum commitments for the Company’s non-cancellable contractual obligations as of September 30, 2023 for non-lease components were as follows (in thousands):

Year Ending December 31,
Remaining of 2023	$	1,307
2024	4,240
2025	2,623
2026	2,603
2027	2,679
Thereafter	6,330
Total future minimum commitments	$	19,782

Rental expense related to the Company’s operating leases for both lease and non-lease components was $2.1 million and $1.9 million for the three months ended September 30, 2023 and 2022, of which $1.8 million and $1.4 million is included in cost of revenue in its condensed consolidated statement of operations, respectively. Rental expense related to lease components was $0.7 million for each of the three months ended September 30, 2023 and 2022. Total operating lease cost was $2.6 million and $2.3 million for the three months ended September 30, 2023 and 2022, respectively, which does not include costs related to services.

Rental expense related to the Company’s operating leases for both lease and non-lease components was $6.2 million and $4.7 million for the nine months ended September 30, 2023 and 2022, of which $5.1 million and $3.6 million is included in cost of revenue in its condensed consolidated statement of operations as of such dates, respectively. Rental expense related to lease components was $2.2 million and $2.0 million for the nine months ended September 30, 2023 and 2022, respectively. Total operating lease cost was $7.9 million and $5.8 million, for the nine months ended September 30, 2023 and 2022, respectively, which does not include costs related to services.

Other Contractual Commitments

Other non-cancellable commitments relate mainly to service agreements used to facilitate the Company’s infrastructure operations. As of September 30, 2023, the Company had non-cancelable purchase commitments of $2.5 million and $0.7 million payable during the remainder of the year ending December 31, 2023 and the year ending December 31, 2024, respectively.

401(k) Plan

The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees. Contributions to the 401(k) plan are discretionary. The Company contributed $0.5 million and $0.4 million to the 401(k) plan during the three months ended September 30, 2023 and 2022, respectively, and $1.4 million and $1.2 million for the nine months ended September 30, 2023 and 2022, respectively.

Legal Matters

The Company is involved from time to time in various claims and legal actions arising in the ordinary course of business. While it is not feasible to predict or determine the ultimate outcome of these matters, the Company believes that there are not any current legal proceedings that are likely to have a material adverse effect on its financial position, results of operations or cash flows. However, the results of legal proceedings are inherently unpredictable and litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.

Accrued VAT Liability

The Company has calculated a liability for uncollected and unpaid VAT, which is generally assessed by various taxing authorities on services the Company provides to its customers. The Company accrues an amount that it considers probable to be collected and can be reasonably estimated. Based on the Company’s analysis, its total accrual for VAT payable was $1.0 million and $1.2 million as of September 30, 2023 and December 31, 2022, respectively.

Indemnification

The Company enters into indemnification provisions under agreements with other parties from time to time in the ordinary course of business. The Company has agreed in certain circumstances to indemnify and defend the indemnified party for claims and related losses suffered or incurred by the indemnified party from third-party claims due to the Company’s activities or non-compliance with certain representations and warranties made by the Company. It is not possible to determine the maximum potential loss under these indemnification provisions due to the Company’s limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. No losses have been recorded in the condensed consolidated statements of operations in connection with the indemnification provisions.

Credit Facility

During April 2022, the Company entered into a second amendment to its revolving credit agreement (as amended, the “RCA”) with City National Bank (“Lender”). Under this amendment, the amount available to be borrowed was increased to $30.0 million from $9.5 million. During January 2023, the Company entered into a third amendment to the RCA. Under this amendment, advances on the line of credit will bear monthly interest at a variable rate equal to, at the Company’s discretion, (a) the average Secured Overnight Financing Rate (“SOFR”) plus 2.00%, or (b) the base rate. The base rate under the RCA is a rate equal to the greater of (i) 3.00% or (ii) the prime rate most recently announced by the Lender. There were no other material changes to the RCA as a result of the amendment. As of September 30, 2023, the Company had an outstanding balance of $6.1 million and the total amount available to the Company to be borrowed was $23.9 million.

Under the RCA, the outstanding balance of $6.1 million as of September 30, 2023 was collateralized by cash held by the Company. As such, the Company held $6.1 million in cash that it deemed to be restricted and is included in restricted cash, current on the Company’s condensed consolidated balance sheet as of September 30, 2023. With prior written notice to the Lender, the Company has the right, at any time prior to the maturity date in September 2024, to terminate the RCA. In the event of such termination, the aggregate principal of the then outstanding amounts, including any accrued interest to date, shall be repaid and the restrictions on the associated collateralized cash would be released. The Company classifies the facility as debt facility, current on its condensed consolidated balance sheet as of September 30, 2023.

As of September 30, 2023, the interest rate associated with the outstanding balance under the RCA was 7.4%, which is a per annum rate. Interest payments on outstanding borrowing are due on the last day of each monthly interest period and payments for the commitment fee are due at the end of each calendar quarter. Total interest expense related to the RCA was $0.2 million and $0.4 million for the three and nine months ended September 30, 2023, respectively. Total interest expense related to the RCA was less than $0.1 million for the three and nine months ended September 30, 2022, respectively.

Insurance Premium Financing Agreement

Effective November 2022, the Company entered into an insurance policy with annual premiums totaling $2.1 million. The Company executed a finance agreement with AFCO Premium Credit LLC over a term of twelve months, with an annual interest rate of 4.5%, that finances the payment of the total premiums owed. The finance agreement required a $0.5 million down payment, with the remaining $1.5 million plus interest paid over three quarterly installments. These quarterly payments started on February 10, 2023. As of September 30, 2023,

Equity [Abstract]

Stockholders' Equity

Stockholders’ Equity Common Stock. From the time of its initial public offering through July 5, 2023, the Company had two outstanding classes of common stock, Class A common stock and Class B common stock. The rights of the holders of Class A common stock and Class B common stock were identical, except for voting, transfer, and conversion rights. On July 6, 2023, all of the Company’s then-outstanding shares of the Company’s Class B common stock were automatically converted (the “Conversion”) into the same number of shares of Class A common stock pursuant to the terms of the Company’s Amended and Restated Certificate of Incorporation. No additional shares of Class B common stock will be issued following the Conversion. In addition, on July 7, 2023, the Company filed a Certificate of Retirement with the Secretary of State of the State of Delaware effecting the retirement of the shares of Class B common stock that were issued but no longer outstanding following the Conversion. As of September 30, 2023, the Company’s sole outstanding class of common stock was its Class A common stock.

The Company had reserved shares of common stock for future issuance as follows:

Equity Incentive Plan

Share Reserve. As of September 30, 2023, the number of shares of common stock available for issuance under the 2021 Equity Incentive Plan equaled the sum of 14,662,500 shares, plus up to approximately 13,719,000 shares subject to awards granted under the 2011 Plan that expire, forfeit or are repurchased following the effective date of the 2021 Plan. In addition, the number of shares reserved for issuance under the 2021 Plan will be increased automatically on the first business day of each of the Company’s fiscal years, by a number equal to the lowest of (i) 4,784,100 shares, (ii) 5% of the shares of Class A common stock outstanding on the last business day of the prior fiscal year; or (iii) the number of shares determined by the Board of Directors. Pursuant to this evergreen provision, the Company increased the number of shares reserved under the 2021 Plan by 809,916 and 411,399 shares of Class A common stock during January 2023 and 2022, respectively.

In general, to the extent that any awards under the 2021 Plan are forfeited, terminate, expire or lapse without the issuance of shares, or if the Company reacquires the shares subject to awards granted under the 2021 Plan, those shares will again become available for issuance under the 2021 Plan, as will shares applied to pay the exercise or purchase price of an award or to satisfy tax withholding obligations related to any award.

Restricted Stock Units

Restricted stock units (“RSUs”) granted under the 2021 Plan generally vest based on continued service over a one-to-four-year period for employees, and over a one year period for non-employee directors.

RSU activity for the nine months ended September 30, 2023 was as follows:

	Shares	Weighted-average grant date fair value per share
Unvested balance as of December 31, 2022	3,716,061	$	6.60
Granted	4,214,704	$	5.04

Unvested balance as of September 30, 2023	5,813,510	$	5.64

Stock Options

Stock Options. Stock options granted under the Company’s equity plans generally vest based on continued service over four years and expire ten years from the date of grant.

The following table summarizes the Black-Scholes option pricing model weighted-average assumptions used in estimating the fair value of stock options granted to employees during the nine months ended September 30, 2022. No stock options were granted during the nine months ended September 30, 2023.

	Nine Months Ended September 30, 2022
Expected term (in years)	6.0
Expected volatility	49.0	%
Risk-free interest rate	1.20	%
Expected dividend yield	—	%

Expected term. For stock options considered to be “plain vanilla” options, the Company estimates the expected term based on the simplified method, which is essentially the weighted average of the vesting period and contractual term, as the Company’s historical share option exercise experience does not provide a reasonable basis upon which to estimate the expected term.

Expected volatility. The Company performed an analysis using the average volatility of a peer group of representative public companies with sufficient trading history over the expected term to develop an expected volatility assumption.

Risk-free interest rate. Based upon quoted market yields for the United States Treasury debt securities for a term consistent with the expected life of the awards in effect at the time of grant.

Expected dividend yield. Because the Company has never paid and has no intention to pay cash dividends on common stock, the expected dividend yield is zero.

A summary of equity award activity under the Company’s equity plans and related information is as follows (in thousands, except share, price and year data):

	Shares available for grant	Outstanding stock options	Weighted- average exercise Price		Weighted- average remaining contractual life (years)	Aggregate intrinsic value
Balance as of December 31, 2022	1,836,566	12,371,281	$	5.74	6.07	$	32,385

The weighted-average grant-date fair value of options granted during the nine months ended September 30, 2022 was $6.26. The intrinsic value of options exercised for the nine months ended September 30, 2023 and 2022 was $6.1 million and $9.1 million, respectively. Aggregate intrinsic value represents the difference between the exercise price of the options

and the estimated fair value of the Company’s common stock at the time of exercise. The aggregate grant-date fair value of options vested was $6.8 million and $8.0 million during the nine months ended September 30, 2023 and 2022, respectively.

As of September 30, 2023, the ESPP reserved and authorized the issuance of up to a total of 956,800 shares of Class A common stock to participating employees. Pursuant to its evergreen provision, the Company increased the number of shares reserved under the ESPP by 667,874 and 607,696 during January 2023 and 2022, respectively.

During the nine months ended September 30, 2023, 348,555 shares of Class A common stock have been purchased under the ESPP. The fair value of the purchase rights under the ESPP was estimated using the Black-Scholes option pricing model with a similar methodology for determining inputs as the Company’s stock options, as described above.

The Company recorded stock-based compensation expense under this plan of $0.9 million and $0.8 million for the three months ended September 30, 2023 and 2022, respectively, of which the Company capitalized $0.2 million and $0.2 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software. The Company recorded stock-based compensation expense under this plan of $2.8 million and $2.4 million for the nine months ended September 30, 2023 and 2022, respectively, of which the Company capitalized $0.7 million and $0.3 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

As of September 30, 2023, the total unrecognized stock-based compensation expense related to the ESPP was $1.8 million and is expected to be recognized over a weighted average period of one year. As of September 30, 2023, $1.2 million had been withheld on behalf of employees, respectively.

The following table summarizes the Black-Scholes option pricing model assumptions used in estimating the fair value of the stock purchase rights under the ESPP during the three and nine months ended September 30, 2023 and 2022, respectively.

During the nine months ended September 30, 2023 and 2022, the Company capitalized $3.7 million and $1.8 million, respectively, of stock-based compensation for the development of internal-use software. As of September 30, 2023, total compensation cost related to stock options and RSUs not yet vested was $13.0 million and $30.4 million, respectively, which will be recognized over a weighted-average period of two years for stock options and RSUs.

Bonus Plan

During March 2022, the Company’s Compensation Committee approved a new bonus structure (“Bonus Plan”) for its employees. The Bonus Plan is contingent upon the achievement of annual corporate performance targets. In each respective calendar year, the Company accrues for the Bonus Plan. The actual payout amount is determined by the Company’s Compensation Committee based on the actual achievement with respect to the annual performance targets and paid in the subsequent year in the variable number of RSUs equal to the payout amount. These RSU’s are fully vested as they were earned (and expensed) prior to the payout. Participants must remain employed with the Company through the date of payout to maintain eligibility under the Bonus Plan.

Pursuant to the Bonus Plan, during February 2023 the Company’s Compensation Committee approved the issuance of approximately 288,000 RSUs that immediately vested based on actual performance against the performance targets for 2022. The Company recognized $0.7 million and $1.7 million in stock-based compensation during the three and nine months ended September 30, 2022, respectively, of which the Company capitalized $0.1 million and $0.2 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

During February 2023, the Company’s Board of Directors approved annual corporate performance targets under its Bonus Plan for 2023 for its employees. If these performance targets are met during 2023, employees will be paid out under the Bonus Plan in RSUs in 2024. As a result, the Company recognized $1.7 million and $2.6 million in stock-based compensation during the three and nine months ended September 30, 2023, respectively, based on progress made towards these performance targets. During the three and nine months ended September 30, 2023, the Company capitalized $0.2 million and $0.4 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software.

Net Loss per Share Attributable to Common Stockholders

Earnings Per Share [Abstract]

Net Loss per Share Attributable to Common Stockholders

Net Loss per Share Attributable to Common Stockholders

The Company computes net loss per share for periods prior to the Conversion using the two-class method required for multiple classes of common stock and participating securities. Prior to the Conversion, shares of Class A and Class B were the only outstanding equity in the Company. The rights of the holders of the Class A common stock and Class B common stock were identical, except with respect to voting and conversion. Accordingly, the Class A common stock and Class B common stock shared equally in the Company’s net losses.

Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potentially dilutive common stock equivalents during the period. For purposes of this calculation, the Company’s stock options, share purchase rights pursuant to the Company’s ESPP, and unvested restricted stock are considered to be potential common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.

As discussed above in Note 12, on July 6, 2023, all of the Company’s then-outstanding shares of Class B common stock, par value $0.0001 per share, were automatically converted into the same number of shares of Class A common stock, par value $0.0001 per share, pursuant to the terms of the Company’s Amended and Restated Certificate of Incorporation. No additional shares of Class B common stock will be issued following the conversion. In addition, on July 7, 2023, the Company filed a Certificate of Retirement with the Secretary of State of the State of Delaware effecting the retirement of the shares of Class B common stock that were issued but no longer outstanding following the Conversion. Prior to the Conversion, the rights of the holders of the Class A common stock and Class B common stock were identical, except with respect to voting, transfer and conversion. As the liquidation and dividend rights were identical, the Company’s undistributed earnings or losses were allocated on a proportionate basis among the holders of Class A and Class B common stock. As a result, the net loss per share attributed to common stockholders was, therefore, the same for both Class A and Class B common stock on an individual or combined basis.

The following table presents the calculation of basic and diluted net loss per share (in thousands, except share and per share data):

	Three Months Ended September 30,								Nine Months Ended September 30,

Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented are as follows:

Restructuring and Related Activities [Abstract]

Restructuring

RestructuringIn January 2023, the Company initiated measures to reduce headcount to pursue greater cost efficiency and align strategic initiatives. These measures were substantially completed by June 30, 2023, and the total cost was $3.6 million. During this period, approximately 1% and 4% of the Company’s workforce terminated employment, which were voluntary and involuntary terminations, respectively. As a result, the Company incurred employee termination expenses and other associated costs.

A summary of the restructuring charges as reported on the condensed consolidated statements of operations for the three and nine months ended September 30, 2023, of which $0.7 million were related to involuntary terminations, is as follows (in thousands):

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company is subject to U.S. federal and state income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter.

The effective tax rate for each of the three and nine months ended September 30, 2023 and 2022 was zero as the Company has incurred continuous operating losses. The Company recorded no income tax provision or benefit during the three and nine months ended September 30, 2023 and three months ended September 30, 2022. The Company recorded an income tax benefit of less than $0.1 million during the nine months ended September 30, 2022.

On August 16, 2022, the Inflation Reduction Act was enacted in the U.S. and introduced a 15% alternative minimum tax based on the financial statement income of certain large corporations (“CAMT”) and an excise tax of 1% of stock repurchases, effective January 1, 2023. There was no impact on the Company’s provision for income taxes from the Inflation Reduction Act for the three and nine months ended September 30, 2023. The Company is continuing to evaluate the various provisions of the Inflation Reduction Act and does not anticipate the impact, if any, will be material to the Company.

Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against its otherwise recognizable net deferred tax assets

Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all disclosures normally required in annual financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the SEC on March 31, 2023. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as its annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of September 30, 2023, results of operations for the three and nine months ended September 30, 2023 and 2022, cash flows for the nine months ended September 30, 2023 and 2022, and stockholders' equity for the three and nine months ended September 30, 2023 and 2022. The results of operations for the three and nine months ended September 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.

Segment Information

Segment Information

The Company has a single operating and reportable segment. In reaching this conclusion, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources, and assess performance. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on an aggregated basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, valuation of the Company’s ESPP expense, and accounting for taxes, including estimates for deferred tax assets, valuation allowance and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates.

Foreign Currency

Foreign Currency

The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company and its subsidiaries is USD. Transaction gains and losses that arise from exchange rate fluctuations on monetary transactions denominated in a currency other than the functional currency are included in general and administrative on the condensed consolidated statements of operations when realized.

Concentrations and Risks and Uncertainties

Concentrations and Risks and Uncertainties

Liquidity. The Company believes that its existing cash, cash equivalents and short-term investments together with cash provided by operations, will be sufficient to support its working capital and capital expenditure requirements for at least the next 12 months. However, to achieve its continued growth and objectives, the Company will need to obtain additional sources of financing which may include entering into lease agreements, sale-leaseback arrangements, credit facilities, and other debt financing arrangements for the purpose of acquiring infrastructure equipment and to fund its operations. In the event that the Company requires additional financing, it may not be able to raise such financing on terms acceptable to us or at all. If the Company is unable to obtain additional sources of financing, raise additional capital or generate cash flows necessary to expand its operations and invest in continued innovation, it may not be able to compete successfully, which would harm its business, results of operations and financial condition.

Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, short-term investments, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and short-term investments with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the balance sheets. In addition, the Company uses City National Bank, a subsidiary of Royal Bank of Canada (“RBC”), for its banking needs. While the Company and its bank has not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption and uncertainty, which could put additional pressures on the Company’s bank and other banks, and may negatively impact the availability and costs for various banking and investment offerings.

Vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply and service disruptions that could harm the Company’s business.

Revenue. The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“Backblaze B2”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact to the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time.

Restructuring

Restructuring

Restructuring costs are comprised of severance costs related to workforce reductions. The Company recognizes restructuring charges when the liability is incurred. For involuntary terminations, employee termination benefits are accrued at the date (i) management has committed to a plan of termination, which includes identification of employees to be terminated and related information, (ii) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn, and (iii) employees have been notified of their termination dates and expected severance payments. For voluntary terminations, the Company recognizes a liability when the termination benefit has been irrevocably accepted by the employee.

Investments

Investments

The Company holds all investments on a held-to-maturity basis, and they are reported at amortized cost with realized gains or losses reported in earnings. The Company determines the appropriate classification of its investment in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date.

The Company will recognize an allowance for estimated credit losses on its held-to-maturity securities, using a forward-looking expected loss model, which reflects losses that are expected to be incurred over the life of the financial instrument. The Company uses a roll-rate method to determine the estimated credit losses using factors including historical global average default rates and expected recovery rates on similar credit quality, bond maturity and duration, along with historical experience, current conditions, and forecasts of future economic conditions, if available. The Company monitors the credit profile of its held-to-maturity securities on a periodic basis, using third party data to assess their credit ratings as well as any adverse conditions specifically related to the security.

The Company’s short-term investments include investment grade commercial paper with original maturities of 365 days or less at the date of purchase. Short-term investments are recorded at amortized cost on the balance sheet.

Accounting Pronouncements Recently Adopted

Accounting Pronouncements Recently Adopted

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires a financial asset measured at an amortized cost basis to be presented at the net amount expected to be collected, with further clarifications made more recently. For accounts receivables, unbilled receivables, loans, and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2023 using the modified retrospective transition method with comparative periods continuing to be reported using the previous applicable guidance and determined that it did not have a material impact on its condensed consolidated financial statements.
